Twinning-induced texture weakening in Mg alloy and its consequent influence on ductility and formability

Abstract

In this study, the room temperature formability of AZ31-0.5Ca was significantly enhanced by pre-deformation to 5% plastic strain. The pre-deformed samples showed the evolution of boundaries related to [Formula: see text] tension twins resulting in weakening of the strong basal texture and leading to excellent improvement in the formability. The pre-induced twining can be considered to be an effective approach to control the texture and enhance the formability of Mg alloy.
