Enhancement in mechanical properties through an FCC-to-HCP phase transformation in an Fe-17.5Mn-10Co-12.5Cr-5Ni-5Si (in at%) medium-entropy alloy

•A low-cost medium-entropy alloy (MEA) composed with a single FCC structure was obtained.•Deformation-induced martensitic transformation (γ-FCC → ɛ-HCP) occurred in the MEA.•CCryogenic environment leads to dislocation dissociation and profuse stacking faults.•Cryogenic-deformed MEA illustrates a yie...
