Abstract

It is well understood that twinning during deformation plays an important role in deformation of Mg and its alloys [1–8]. In hexagonal close packed (HCP) Mg alloys, the dominant deformation mode at room temperature is <a> slip on the basal (0001) plane Mg [9, 10]. The other slip systems—prismatic <a> slip, pyramidal <a> slip, and pyramidal <c + a> slip—require much higher stresses to activate during deformation [11]. Mechanical twinning allows for grains to easily deform along their c-axis [12] and has been the focus of significant, active research [e.g., 13–23].
