Abstract

V rámci práce byl studován zajímavý případ exfoliace hliníkové slitiny. Jednalo se o expresní karabinu exponovanou v prostředí krasové jeskyně. Jednotlivé části jisticí sady byly sledovány na metalografických výbrusech pomocí optického i skenovacího elektronového mikroskopu s rentgenovou energiově disperzní analýzou (SEM/EDS). Korozní produkty byly analyzovány metodou rentgenové difrakce (XRD). Příčinami selhání karabiny bylo nevhodné termomechanické zpracování a expozice v trvale vlhkém prostředí.
