中文摘要	The deformation of the Mg alloy AZ31 has been investigated in the temperature range from room temperature to 250 degrees C. Microstructural investigation of samples compressed at 150 degrees C showed extensive twinning only in samples where the basal plane normals were initially aligned approximately perpendicular to the compressive stress axis. Despite the large differences in microstructure for compression at this temperature, no significant differences were seen in the ductility. Grain rotations were observed in the non-twinned parts of some twinned grains after a strain of just epsilon=0.1. These rotations limit the extent to which the twinning behaviour can be related to the grain orientation. To interpret the twinning behaviour it is necessary to pay attention to boundaries formed by the intersection of two twin systems within a given grain.
