%X The modifications of basal texture in AZ31 magnesium alloys processed by asymmetrical rolling and equal channel angular rolling (ECAR) are investigated. Deformation mechanisms are determined by microstructure observation and macro- and micro-texture measurements. Results show that during asymmetrical rolling the basal texture is gradually rotated around TD (transverse direction) by basal slip activated by shear strain on the rolling plane, whereas the prism texture is induced by tension twinning activated by shearing parallel to the plane separating the two channels during ECAR. So both the special processing techniques may improve the plasticity of magnesium alloy. The effects of rolling reduction and annealing on textures are also studied and discussed.
