FCC-HCP martensitic transformation is a known cause of transformation-induced plasticity in high manganese steels and shape memory effects in Fe-Mn-Si shape memory alloys. This paper describes the shape memory effect due to FCC-HCP martensitic transformation in Cr20Mn20Fe20Co40-xNix high-entropy alloys.Deformation behavior and low-cycle properties were investigated for Co51-xCr23Mo6Nix medium-entropy alloys. Alloys that underwent FCC-HCP martensitic transformation simultaneously with deformation twinning exhibited improved low-cycle fatigue life.
