摘要：

The effects of differential speed ratio on the microstructure and the texture of AZ31 magnesium alloy sheets processed by differential speed rolling (DSR) were investigated by optical microscopy and X-ray diffraction analysis. The results show that differential speed ratio has a significant effect on the grain morphology but a little influence on the grain size. As the differential speed ratio increases to 2.800, lots of long-strip grains are found. The intensity of {0002} basal textures is much higher on the side of fast rolling than on the side of slow rolling and the distributions of {0002} orientations are different between the two surfaces of the sheet. Differential speed ratio has also a great influence on the strength of basal textures and when the differential speed ratio increases, the intensity of {0002} basal textures increases firstly and then reduces. This special texture change could be attributed to shear deformation introduced throughout the thickness during the differential speed rolling process. © Right.
