Enhanced strength-ductility synergy in a gradient hetero-structured CrCoNi medium-entropy alloy

A CrCoNi medium-entropy alloy (MEA) with gradient hetero-structure (GHS) composing of gradient nanostructured surface layer and hetero-structured matrix was prepared via a two-step process: pre-cold rolling (CR) deformation and subsequent annealing followed by surface mechanical grinding treatment (...
