Microstructure and defect structure evolution in ultra-fine grained MgAlZn alloy

Abstract

Commercial MgAlZn alloy AZ31 was processed by two techniques of severe plastic deformation, namely equal channel angular pressing (ECAP) and high pressure torsion (HPT). Microstructure evolution with strain due to ECAP and HPT was investigated by light and transmission electron microscopy (TEM).
