Effect of pre-deformation on the activation stress of {10–12} twinning in Mg–3Al–1Zn alloy

Wrought magnesium and Mg alloys are characterized by a strong basal texture and several slip and twin modes activated at room temperature. These modes interact with each other, and the obstacles on each system associated with other deformation systems are empirically modeled via latent hardening coupling coefficients. { 10 1 ‾ 2 } tension twinning can be easily and largely activated, causing severe mechanical anisotropy and dramatic texture …
