AbstractThis paper investigated the mechanical properties and texture evolution of extruded AZ31 magnesium alloy rods under cyclic torsion. Thus, cyclic torsion tests were performed at different temperatures such as room temperature, 373, 443, 503, and 573 K. Measured mechanical properties of magnesium alloy cyclic torsion reveal that stress-strain hysteresis loops of cyclic torsions are strictly symmetric which means that the dominant deformation mechanism is sliding. Additionally, due to the thermal influence of cyclic torsion, the peak stresses in stress-strain hysteresis loops are decreased with the increase in cycle number. The grain orientations are changed due to the activation of prismatic slips. The texture of {11 (2) over bar0} prismatic planes perpendicular to ED in initial rods is transformed into the texture of {10 (1) over bar0} prismatic planes after cyclic torsion. Also, two types of grain orientation variations occur because of the activation of extension twin.
