采用单向轧制和不同轧制参数的斜轧工艺制备了AZ 31镁合金板材，并对退火后板材的显微组织和力学性能进行了研究.结果表明，单向轧制时，在总变形量相同的情况下，各道次大变形的退火板材具有更细小的显微组织.斜轧降低了镁合金板材的室温各向异性，斜轧后板材组织更加均匀，冲压性能更好;单向轧制和斜轧对镁合金板材组织的细化效果相似。
AZ31 magnesium alloy sheets were produced by unidirectional rolling and cross rolling with different rolling parameters.Microstructure and mechanical properties of the rolled sheets after annealing were examined.The results indicate that for the unidirectional rolling,under the same total deformation strain,the annealed sheets heavily deformed in every pass have finer microstructure. Cross rolling decreases the anisotropy of magnesium alloy sheets at room temperature.Sheets processed by cross rolling exhibit more homogeneous microstructure and better performance for stamping.Unidirectional rolling and cross rolling have the similar refining effects on microstructure of magnesium sheets.
