Description

An equiatomic CoCrFeNiMn high entropy alloy was subjected to high-pressure torsion under a pressure of 10 GPa at room and cryogenic temperatures. Increasing straining and decreasing the deformation temperature led to deformation-induced FCC to HCP and BCC martensitic transformations, which played a significant role in the strengthening of the alloy.
