| Abstract Scope |
Five Cantor-derived alloys with four elements in equiatomic composition were investigated to establish their dynamic performance: CrMnFeNi, MnFeCoNi, CrMnCoNi, CrMnFeCo, and CrFeCoNi. Under identical homogenization, deformation, and recrystallization treatments, they exhibited significant differences in the microstructure and mechanical response, which was established through compression experiments with strain rates ranging from 10-4 to 10 3 s-1. Spalling experiments conducted using a gas gun and flyer plate impact at velocities in the 1,000 m/s range yielded recovery of the specimens for characterization of the failure initiation sites while VISAR measurements using the pullback signals enabled the measurement of the tensile strengths under uniaxial strain and an applied strain rate of 106 s-1. The differences in mechanical response are correlated with the microstructural features. |
