{ 10 1 ¯ 2 } twinning behavior under biaxial tension of Mg–3Al–1Zn plate

Although { 10 1 ¯ 2 } twinning behavior has been extensively studied, it has rarely been investigated under biaxial tension. In the present research, the mechanical response and { 10 1 ¯ 2 } twinning behavior of a Mg AZ31 sheet under biaxial tension with various stress ratios ( σ N D : σ T D ) along the normal direction (ND) and transverse direction (TD) were systematically studied. The results indicate that the yield stress along the ND is …
