对商用AZ31镁合金板材进行了正轧辊轧制和横轧辊轧制的比较，其中轧辊轴在RD-TD平面上与TD倾斜7.5°。与正常轧制试样相比，横轧试样的织构发育明显，晶粒尺寸和织构的厚度梯度减小。变形板材织构在整个厚度上的均匀性是镁合金板材成功变形的关键因素。通过对正轧和横轧试样的直接比较，讨论了织构发展和相应的组织。
Normal and cross-roll rolling were compared for commercial AZ31 magnesium alloy sheets, where the roll axis was tilted by 7.5° against TD in the RD–TD plane. In the cross-rolled specimens, the texture strongly developed and the through-thickness gradient of grain size and texture decreased compared with the normally rolled specimens. The homogeneity of the texture throughout the whole thickness of the deformed sheet is a key factor in the successful deformation of Mg sheets. The texture development and corresponding microstructures were discussed in terms of the direct comparison of the normal and cross-roll rolled specimens.
