Abstract
The results of molecular dynamics simulations of the self-diffusion coefficient (SDC) and viscosity coefficient (VC) of liquid nickel (Ni) in a temperature range of 1720 – 2500K are presented. The temperature dependence of the SDC is determined numerically by molecular simulations with the Embedded Atom Method Finnis-Sinclair (EAMFS) potential as implemented in the Virtual Nano Lab 2017.2. The temperature dependence agrees with the Arrhenius law. Results obtained for SDC are found to overestimate available experimental results, while results for VC underestimated experimental values. Also, the validity of Stokes-Einstein relation was tested in liquid Ni and was found to be valid at all temperatures.
