Laser welding, thanks to the use of oscillating heads, is finding increasing use in modern industry. Laser oscillating welding heads offer numerous advantages over traditional laser welding heads. Currently, industries where preparing components for laser welding was previously a significant challenge can now adopt this welding technique thanks to the use of oscillation. The ability to improve the properties of welded joints, autogenous welding, and a high level of process automation make laser welding technology a promising industry. Unfortunately, the complexity of multidimensional processes, already difficult to apply, combined with the wide range of possibilities for modifying beam oscillation, requires a deeper understanding of the impact of new laser welding parameters on the quality of welded joints for industrial implementation. This article presents the results of studies on the microstructure of austenitic stainless steel welded with a laser beam at various welding beam oscillation parameters. The welds were obtained using a ytterbium QCW (Quasi Continuous Wave) fiber laser autogenous (without the use of the filler material). The test material was 4 mm thick AISI 304 austenitic stainless steel sheets as delivered. The aim of this study was to investigate the effect of oscillation parameters such as frequency, amplitude, and shape used during laser welding on weld geometry. Statistical relationships between the studied variables were identified. Laser power exhibits strong positive correlations with key weld geometry parameters, particularly penetration depth (H: r = 0.66), weld face width (B: r = 0.79), and cross-sectional area (S: r = 0.80). In contrast, laser beam oscillation parameters show a negative correlation with penetration depth (H: r = −0.48) and a moderate correlation with weld face width (B: r = 0.56). Other oscillation related effects demonstrate only weak correlations (r ≤ 0.38) with weld geometry. Mathematical models describing these relationships were developed and their quality verified. The presented models enable the prediction of the transverse shape dimensions of welds based on known welding parameter values.

The Underwater Friction Stir Welding (UFSW) environment was proven to improve mechanical properties of the Friction Stir Welded (FSW) joints. However, carefully selected set of parameters is necessary to succeed. This study presents preliminary results of the research on water salinity level effect on the properties of the AA5754 aluminum alloy joints. For this purpose, the Plackett-Burman design was used. The design of experiment consists of ten attempts with process parameters as variables: welding speed, rotational speed, tool tilt angle and water salinity level. The following tests were proceeded: visual tests, tensile strength tests and fractography analysis. Thus, the response variable was ultimate tensile strength (UTS). Surface defects were found in joints performed with low heat input (i.e. low rotational speed, high welding speed). The highest UTS values – 100% of base metal were obtained for the joint made with process parameters: welding speed - 37.5 mm/min, rotational speed - 1235 rpm, tool tilt angle - 2°, water salinity level - 10%. The fractography of the joint revealed precipitates formation and very small dimples. All of the investigated welding parameters were found to be statistically significant. However, the tool tilt angle was of drastically highest significance. The order of the other process parameters was as following: welding speed, rotational speed and water salinity level.

            <description><![CDATA[

In this study, we present a comprehensive machine learning-based approach for optimizing alloy compositions with the goal of simultaneously maximizing Ultimate Tensile Strength (UTS) and approaching a target Melting Completion temperature. Using a dataset comprising elemental compositions of various alloys and their corresponding mechanical properties, we developed predictive models based on the Random Forest Regressor algorithm. SHAP (SHapley Additive exPlanations) and LIME (Local Interpretable Model-agnostic Explanations) were employed to interpret the feature contributions and determine the most influential elements on both UTS and melting behavior. The analysis revealed that elements such as Fe, Mn, Co, and Mo significantly contribute to optimal alloy performance, while elements like C and V play a critical role in enhancing UTS. A multi-objective optimization was conducted using a Genetic Algorithm (GA), yielding an optimal composition that achieved a predicted UTS of 1520.7 psi and a Melting Completion temperature of 1407.4°C, closely aligned with the target of 1460°C. Our approach demonstrates the potential of combining interpretable machine learning with evolutionary optimization to accelerate intelligent alloy design and discovery.

This study examines the influence of print orientation and printing speed on the mechanical strength and surface roughness of components fabricated from Polylactic Acid (PLA) using the Fused Deposition Modeling (FDM) process. The 3D-printed samples were produced with varying orientations (0°, 90°, and 45°) and print speeds, while other parameters remained constant. All samples had a 100% infill density, a “Lines” infill pattern, and a printing temperature of 210°C. The 0° and 90° samples were printed at 50 mm/s, whereas the 45° samples were printed at 40, 60 and 80 mm/s. Each sample was printed three times to ensure repeatability and obtain an average result. The results indicate that raster angle plays a critical role in determining mechanical performance, with 0° and 90° orientations yielding the highest 72.31 MPa and lowest 56.26 MPa stress values, respectively. Additionally, a nuanced relationship was observed between printing speed, surface roughness, and tensile strength. Surface roughness metrics, including Ra, Rz, and Rq, improved with decreasing printing speed, indicating enhanced surface finishes. The optimal tensile strength of 57.95 MPa was achieved at a moderate printing speed of 60 mm/s, offering the best balance between mechanical strength and surface quality. This research enhances the understanding of parameter optimisation in FDM processes, providing practical insights for the production of high-performance PLA-based components.

This study examines the influence of psyllium husk flour (PF) on the structure and physical properties of thermoplastic starch (TPS) films. Films with 2 g and 6 g PF were produced using the casting method. Their morphology was analyzed by stereoscopic, scanning electron, and atomic force microscopy, while mechanical and wettability properties were evaluated. Increasing PF content improved impact strength but also increased brittleness. Higher PF concentration raised the water contact angle and reduced its change over time. The results indicate that psyllium husk flour effectively enhances the functional performance of TPS films, supporting their potential for sustainable packaging applications.

            <description><![CDATA[

Tungsten Inert Gas (TIG) welding constitutes a key process in the fabrication of welded structures, with widespread application across various sectors of modern industry. It continues to be the subject of extensive research due to its technical advantages and versatility. However, despite its industrial importance, TIG welding has not yet been the focus of a comprehensive bibliographic review. Therefore, the objective of this study is not only to present the current state of knowledge but also to identify key process directions and emerging research trends through a bibliometric analysis of 8,789 publications indexed in Web of Science. The analyses were performed mainly in VOSviewer 1.6.20 and Biblioshiny tools, determining the networks of connections between bibliometric entities: keywords, journals, authors, countries, and funding agencies. The analysis results were used to illustrate the dynamics of research topics over a 60-year publication history on the TIG process. Current research trends include, among others, the advancement of TIG welding variants to improve process efficiency, the application of artificial intelligence, the application of optimization methods, and deep learning. The most urgent research needs involve determining the weldability of special metals, assessing the environmental degradation of TIG-welded joints, and applying data mining techniques for the optimization of the TIG process. The study may serve as an objective, comprehensive, and author-unbiased complement to traditional systematic review articles on TIG welding and related processes.

MAO processing of titanium biomaterials for long-term implants forms oxide layers resistant to mechanical stresses during surgery, making them among the best surface modifications. Bioactivity can be enhanced using electrolytes with calcium, phosphate, or apatite; mechanical and corrosion properties can be improved by adding other compounds. This study examines effects of voltage, current, deposition time, hydroxyapatite (HA) and multi-walled carbon nanotubes (MWCNTs) in the electrolyte on Ti13Nb13Zr alloy surface properties. Methods included SEM, EDS, profilometry, hardness, corrosion, and wettability tests. CNTs improved mechanical properties, reduced corrosion resistance, slightly affected wettability. Voltage controlled plasma oxidation intensity; current affected ion/molecule mass flux.

            <description><![CDATA[

This study presents the fabrication and characterization of functionally graded Al2O3-Ni ceramic-metal composites using centrifugal gel casting with 2-carboxyethyl acrylate (CEA) as the monomer. Two Series of composites were produced under different centrifugal conditions to investigate their influence on nickel distribution, microstructure, and mechanical performance. The CEA-based gel system enabled the formation of dense green bodies with improved phase dispersion and sintering behavior. Microstructural analysis revealed that lower rotational speed and longer casting time (2500 rpm, 110 min) led to a more uniform radial distribution of nickel particles and reduced agglomeration. This microstructural improvement resulted in significantly higher compressive strength (1620 kN) compared to the faster cast series (977 kN). Digital image correlation confirmed more distributed strain fields and delayed fracture in the optimized samples. These findings demonstrate that casting parameters and monomer chemistry can be effectively tailored to engineer dense, robust, and gradient-structured ceramic–metal composites for high-performance applications.

In this study, graphite (Gr) nano flakes dispersion with increasing number of passes (1, 2, and 3) inside the resultant aluminium ENAW-6061-O-Gr composites using Friction Stir Processing (FSP) has been accomplished successfully. The objectives were to embed the Gr nanoflakes inside ENAW-6061-O-Gr composites, investigate the effect of number of FSP passes on the mechanical properties of aluminium 6061/graphite composites. The ENAW-6061-O-Gr composite samples were evaluated with tensile tests and elemental analysis through SEM with EDX and mapping. The dispersion and presence of graphite particles is confirmed. Multi-pass FSP improved the tensile strength of the ENAW-6061-O-Gr composites. The UTS of C3-Composite processed with three passes is 153.65 MPa, that is 24% of improvement compared to the unreinforced aluminium ENAW-6061-O base metal alloy.

            <description><![CDATA[

The present review article is planned to systematically unfold salient worth of three dimensional graphene based polymeric nanocomposites for radiation shielding (electromagnetic, nuclear, gamma, fast neutrons) purposes. As per literature reports so far, we discuss polymer/three dimensional graphene nanocomposites for variety of thermoplastic, thermoset, and conjugated matrices employed for related high end material designs. Accordingly, multifunctional hybrids of three dimensional graphene have been fabricated via facile/resourceful fabrication techniques, including solution processing, in situ method, melt technique, freeze drying, hydrothermal tactic, printing, foaming, and allied synthesis procedures. The ensuing three dimensional graphene based hybrids/nanomaterials have been analyzed for microstructural, structural integrity, electron/charge conduction, dielectric features, permittivity, radiation shielding effectiveness, shielding efficiency, and other features desirable for nuclear/gamma/electromagnetic radiation protection application. Besides, underlying mechanisms of radiation attenuation have also been argued, as per scientific surveys. It seems that performance of hierarchical graphene nanoassmblies relies upon nanoarchitectural adaptability, interfacial interactions/wettability, and structure-property synergies. Eventually, inimitable polymer/three dimensional graphene nanocomposites have been found promising to meet technological demands of radiation shielding in aeronautics, devices, defense, and nuclear power plant industries. Despite practical success of radiation shielding three dimensional graphene hybrids, in spite of pristine graphene, future deployment in related industrial modules seems to be connected to focused experimental/theoretical endeavors by field researchers to overcome underlying design/property/performance challenges.

The machinability of two copper alloys with lead: CuZn40Pb2 and CuSn5Zn5Pb2, was assessed. Turning tests were performed based on the selection of parameters that will result in the tool being worn out after 1 minute. Tool wear was assessed by observing dimensional and microstructural changes in the blade. When assessing machinability, power consumption, chip shape, changes in the surface layer and surface roughness were taken into account. The research aims to determine the custom machinability index of materials used in SANHA Polska. A publicly available index must be adapted to a given application, and such adaptation is often quite time-consuming. Therefore, a 1-minute test was carried out as a quick and cheap alternative to a large fleet of machines with various machining properties. The developed methodology and the results obtained are the basis for further research conducted as part of the implementation doctorate, the aim of which is to implement the production of well-machinable lead-free materials for drinking water installations, characterized by good solderability and corrosion resistance. As a result of the conducted research, the role of lead in the machining of copper alloys was identified, which is important due to European restrictions on the elimination of this element and its replacement in a way that allows for precise removal processing.

This study aims to investigate and optimize the thermal dissipation of a constant heat flux source by conducting a numerical analysis of four serpentine mini-channel heat sink configurations, each characterized by different inlet and outlet arrangements for the cooling fluid. The cooling system under study consists of an upper part made of ABS copolymer resin, incorporating the fluid inlets and outlets (water), and a lower part made of aluminum, which contains the serpentine mini-channel heat sink. The analyzed configurations included four cases: First: a single inlet and a single outlet, Second: two inlets and one outlet, Third: one inlet and two outlets, and Fourth: a variation of the third model with reversed inlet and outlet positions. Numerical simulations, performed using the finite volume method, cover a Reynolds number range from 200 to 600. The analysis focuses on flow behavior, temperature distributions, pressure drop, thermal resistance, the average Nusselt number and the performance evaluation factor (PEF). The results indicate that the configurations with two inlets and one outlet (Case 2) and the reversed inlet/outlet configuration (Case 4) significantly enhance cooling compared to the other configurations. However, the two-inlet, one-outlet case also results in a higher pressure drop. At a Reynolds number of 600, Case 2 achieves the best thermal performance with an average Nusselt number of 20.79 and a minimum thermal resistance of 0.228K/W, while Case 3 exhibits the lowest efficiency. These findings help identify optimal configurations for cooling high heat flux electronic components.

This work focuses on improving the mechanical strength and corrosion resistance of Aluminum (Al) AA6063 alloy, which is limited by its moderate hardness and exposure to acidic conditions. The main aim of this study is to examine the effect of Titanium Dioxide (TiO₂) and Tungsten Carbide (WC) particles on the hardness and acidic immersion corrosion of AA6063 alloy-based monolithic and hybrid Metal Matrix Composites (MMCs), which were manufactured via stir casting with a fixed 5 wt.% TiO₂ and varying wt.% of WC (0, 0.5, and 1 wt.%), followed by T6 heat treatment at different aging temperatures of 145°C, 165°C, and 185°C. The microstructural exploration using Hi-Resolution Scanning Electron Microscopy (HRSEM) and Energy-Dispersive X-ray Spectroscopy (EDS) showed an even dissemination of reinforcements. X-ray Diffraction (XRD) observed the occurrence of Al, TiO₂, WC, and Mg₂Si phases. Taguchi’s methodology optimized the Vicker’s hardness and Corrosion Rate (CR), considering aging temperature and wt.% of WC as the input variables. Analysis of Variance (ANOVA) results indicated that the variation in WC content had a more significant effect on both hardness and CR than the aging temperature. The 165°C aged samples produced high hardness and lower CR due to the Silicon (Si) spheroidization. The HRSEM examination of corroded surfaces revealed fewer signs of deep pits at lower CR conditions. The results indicate that the selective incorporation of WC and TiO₂ can improve the performance of AA6063 composites in corrosive environments.

            <description><![CDATA[

Recently, we note, high entropy alloys have attained incalculable research curiosity owing to remarkable elemental combinations, microstructural features, phase structure/stability, and superior physical characters mainly mechanical, thermal, and corrosion resistance under extreme working conditions. Interestingly, these materials have been found capable of sustaining the mechanical and anticorrosion properties at considerably high temperatures. In addition to the energy, engineering, and biomedical fields, high entropy alloys have been frequently explored for radiation protection applications. In nuclear sector, high entropy alloys and nanocomposite alloys exhibited worthy radiation defense towards wide ranging energetic particles including fast neutrons, gamma rays, electrons/ions, and other radionuclides. Consequently, plentiful high entropy alloys and related nanomaterial (nanocarbons, polymers, inorganic) designs have been found promising as functional bulk material/coatings for nuclear radiation as well as electromagnetic interference defiance. Accordingly, the appropriate experimental as well as theoretical approaches have been applied to study the structure, durability, and nuclear shielding effectiveness. In this context, various active mechanisms have been reported, including the micro-level changes, phase transformations, reduced thermal conductivity, and related radiation induced effects. Henceforth, this all-inclusive state-of-the-art overview, we believe, enlightens the significance of high performance high entropy alloys and nanomaterials for technical radiation defense applications against nuclear and electromagnetic interfering irradiations. In addition to radiation shielding parameters, the next generation high entropy alloy shields have been surveyed for synergistic mechanical, thermal, and anticorrosion features desirable against extreme nuclear/fission reactors environments.

The process of edge preparation for welding plays a crucial role in ensuring the quality of welded structures, affecting both their mechanical properties and overall economic efficiency. The aim of this article is to present a comparative analysis of traditional oxy-fuel cutting and modern milling methods for edge preparation of S355J2N low-alloy steel, focusing on surface quality, microstructural changes, as well as economic aspects. The study was conducted on plates with thicknesses ranging from 8 to 20 mm, using bevel angles of 30° and 45°. Both straight and curved beveled edges were investigated, utilizing a self-propelled OMCA 900 beveling machine, Gerima MMB 400B and SMA 60 BER milling machines, and a PERUN PC-211A/Y11 gas torch. Surface roughness measurements, macroscopic analysis of the edges, and HV1 microhardness testing were performed. Operation times were recorded to enable a cost analysis.
The results demonstrated that milling significantly reduces edge roughness—Ra values decreased by a factor of 6 to 10 compared to oxy-fuel cutting. In the case of oxy-fuel cutting, a heat-affected zone approximately 2–3 mm thick and localized surface hardening up to 250–450 HV1 were observed, while milling did not cause changes in hardness. Cost analysis showed that under Polish labor rates, the total beveling costs were comparable for both methods (approximately 2 EUR/m), whereas under average EU labor rates, milling became the more economically viable solution.

This study investigates the effects of using crumb rubber as a partial replacement for dune sand in concrete mixtures. The incorporation of crumb rubber presents promising ecological and economic benefits, particularly for waste management and material sustainability. In this research, up to 5% of the dune sand was replaced with crumb rubber, and the resulting concrete’s fresh and hardened properties were thoroughly examined to evaluate the impact of this substitution on its mechanical characteristics. The findings reveal that concrete mixtures containing crumb rubber exhibit significantly reduced compressive strength, with a comparatively smaller decrease in tensile strength, relative to conventional dune sand concrete. Specifically, at a 5% replacement rate, substantial reductions in compressive and tensile strength were observed at 28 days, amounting to 66.15% and 48.72%, respectively. These performance limitations suggest that crumb rubber-modified concrete may not be appropriate for structural applications. Nevertheless, potential alternative uses, such as in highway median barriers, curbs, or decorative elements, could represent viable applications for these modified concrete mixtures.

Architected metamaterials utilize unique geometries to enhance the mechanical and physical properties of structures. This study investigates the energy absorption capabilities of additively manufactured hybrid strut-based metamaterials, produced using Fused Deposition Modeling (FDM) with Polylactic Acid (PLA). Compression tests were conducted on six novel hybrid strut lattice designs to analyze their structure-property relationships. The designs integrated Kelvin cells, edge struts, octagonal shapes, hex trusses, face-centered components, and corner diagonal struts. The combination of “Kelvin Cell + Octagon” achieved excellent energy absorption efficiency, with the highest Specific Energy Absorption (SEA) of 1450 kJ/kg. Through the synergistic effect of octagonal geometry and Kelvin cell structure, controlled deformation and delayed buckling are realized to release the energy fully and maximize stress wave interaction. However, the configuration of the “Edge Struts + Hex Truss” configuration was not far away either, exhibiting an SEA of 1388.89 kJ/kg, owing to the effective load distribution provided by the hexagonal truss structure. Other configurations had much lower SEA values: 275 kJ/kg for “Kelvin Cell + Hex Truss” 185.71 kJ/kg for “Kelvin Cell + Edge Struts” 162.5 kJ/kg for “Edge Struts + Corner Diagonal” and 26.67 kJ/kg for “Edge Struts + Face Centre”. Using microscopy to look at failed samples showed that shapes with hexagonal and octagonal parts increased SEA by making stress distribution more even and limiting deformation during compression. The unit cell geometry is the critical factor for deciding upon the energy absorption capacity of metamaterials. This work provides useful insights to design optimized additively manufactured metamaterials to achieve high energy absorption, which will be useful to applications such as automotive crash protection, aerospace components, personal protective equipment, and vibration damping systems. The “Kelvin Cell + Octagon” and “Edge Struts + Hex Truss” configurations emerge as highly effective designs, balancing strength, ductility, and energy absorption efficiency for advanced engineering applications.

Flexible electronic devices, such as OLEDs, flat panel displays (FPDs), and photovoltaic solar cells, frequently employ transparent conductive electrodes composed of indium tin oxide (ITO)/Ag-alloy/ITO-coated polymer films. However, the films are subjected to a combination of thermal and mechanical forces, particularly bending around rolls, during roll-to-roll manufacturing. This can result in thin film failure. Furthermore, these films are curved around the surface of flexible electronic devices, such as solar cells, during operation. Furthermore, they can be in service in hot and humid locations for extended periods throughout the summer, such as deserts. These stresses can lead to the degradation of the device’s performance by causing cracks in the conductive thin films and corrosion of the Ag-alloy layer over time.
In this work, ITO/Ag-alloy/ITO films were bent under tensile mode to different radius of curvature over a period of time at different humidity and temperature levels. The electrical resistance was measured in situ, and four combinations of temperature and relative humidity were used: 25°C, 65°C, and 25 percent and 80 percent. According to the results, irrespective of the temperature level, high humidity causes the films to degrade more quickly. Particularly, the films exhibited a notable increase in normalized electrical resistance when subjected to a 4.3 mm radius of curvature in both high temperature and high humidity conditions. This was associated to aggregation of the silver layer, film buckling, and crack formation. Furthermore, the film’s conductivity was further reduced by surface cracks that allowed oxygen and moisture to penetrate. Consequently, to maintain the integrity of the film, an external applied stress with moisture and/or harsh environments as well as moisture and/or harsh environments alone should be avoided during both manufacturing and application processes.

This study explores how the addition of copper (Cu) addition impacts the microstructural and thermal properties of shape memory alloys (SMAs), specifically TiNiPd alloys. Two compositions, 0Cu and 10Cu, were analyzed using X-ray diffraction (XRD), scanning electron microscopy (SEM), Optical Microscopy (OM) and differential scanning calorimetry (DSC). SEM revealed second-phase precipitates distributed along grain boundaries in both alloys, with sizes ranging from 0.9 to 2.9 μm; however, Cu addition reduced precipitate density without affecting size. The grain size increased significantly from 12.5 μm in 0Cu to 17.5 μm in 10Cu, attributed to decreased nickel content and reduced pinning effects of precipitates. Aging at 600°C and 700°C further influenced precipitate behavior and transformation temperatures, with Cu-containing alloys demonstrating enhanced thermal characteristics. DSC analysis indicated significant increases in transformation temperatures and decreased thermal hysteresis with Cu addition. These results highlight the promise of Cu as a viable substitute for Ni in enhancing the properties of TiNiPd SMAs.

This study investigates the stop-hole technique for crack repairs in structural parts subjected to fretting fatigue. The drilling of a hole at the crack tip relieves the concentration of stresses around the crack, which prevents further growth. The maximum von Mises stress is considerably reduced by a stop-hole, as can be seen from the analysis. The configuration with a double stop-hole reduces it to 641 MPa with a 50 µm radius. An exploration of different radii shows that a higher radius value increases stress relief, while the best range is between 60–80 µm. To see exactly how this optimal range improves fatigue life, the number of cycles to crack initiation was computed; the optimal range thus significantly extends the repaired component’s lifetime. These findings suggest that stop-hole design optimization may be required to achieve enhanced durability for extending the service life of a fatigued component.
