Plastic deformation behavior of hot-rolled AZ31 Mg alloy under 6 passes plane strain compression along transverse direction (TD) and normal direction (ND) alternatively is systematically study in current paper. With 10% compression along TD, most grains are nearly twinned totally and extension twinning takes place during subsequent compression along ND. Yield stress rises with increased compression passes due to enhanced activation stress for extension twinning by dislocations generated in previous pass of compression. Preferred distribution of prismatic planes appears after each pass of compression besides of the rotation of basal plane poles toward compression axis, which is closely related with extension twinning.
