研究了AZ31B镁合金热轧、冷轧和热处理状态板材织构的特征以及对机械性能各向异性的影响. 结果表明：轧制镁合金板材具有主要以基面织构为主的板织构, 其基面平行于板面, 其他织构组分相对较弱；冷轧后的基极密度中心围绕板横向向轧制方向旋转约18$^{\circ}$; 冷轧后在300℃热处理对织构分布特征影响不大. 冷轧后的基面向轧制方向倾斜使该方向的塑性指标得到改善.
The textures of AZ31B magnesium alloy sheets in the conditions of hot rolling, cold rolling and heat treatment were investigated, and its feature and influence to the mechanical property anisotropy were studied. The conclusions show that the texture of rolled magnesium alloy sheet prefer to basal texture with basal plane parallel to sheet surface, while other compositions of texture are relatively weaker; the density center of basal pole rotates away by about 18$^{\circ}$ from the transverse direction of sheet to rolling direction; to cold--rolling of sheet, there is no significant change of texture distributing after heat treatment at 300℃. After cold--rolling of sheet, the basal plane slopes to rolling direction, improving the ductility in this direction.
