| Abstract | The multi-path compression with sequential RD-ND-RD-ND (RD-rolling direction; ND-normal direction) was performed on the AZ31 magnesium alloy rolled sheet, and mechanical properties during deformation were studied, the electron backscatter diffraction (EBSD) technique was applied to track the grain orientation evolution during the above deformation, and activations of twin variants were analyzed. The results show that the deformation mechanism of {10 (1) over bar2} tensile twin-{10 (1) over bar2} untwin-{10 (1) over bar2} tensile twin and {10 (1) over bar2} untwin are sequentially related to each compression during the above deformation. The yielding strength is significantly decreased during the first untwining, but the yielding strengths are increased for both twinning and untwining during the following deformations, and there are not obvious differences between them. The activation of untwinning follows the Schmid criterion, but there is an obvious selective tendency for twin variant activation, and twin variants t3 or t4 are activated to start the untwinning. |
