The deformation behavior and strain rate sensitivity of ultra-fine grained CoNiFeCrMn high-entropy alloys at temperatures ranging from 77 K to 573 K

In this study, CoCrFeMnNi (Cantor alloy) high-entropy alloy (HEA) with ultra-fine grained (UFG) structure were prepared using cryogenic (liquid nitrogen, 77 K) rolling followed by short time annealing. The deformation behavior and strain rate sensitivity (SRS) of processed material were investigated...
