摘　　要：对AZ31镁合金板材进行了703、733、763、793K的轧制,研究了高温轧制弱化基面织构如何提高镁合金板冲压成形性能。结果表明,在实验条件下,随着轧制温度的提高,镁合金板材晶粒尺寸长大,强度降低,断裂伸长率减小,而其杯突值获得极大的提高。这主要与基面织构的弱化、基面滑移容易开动有关。The AZ31 magnesium alloy plates were rolled at 703,733,763 and 793K. How to improve the formability of magnesium alloy plate by high temperature rolling weakening the substrate texture was studied. The results show that under the experimental conditions, with the increase of rolling temperature, the grain size of magnesium alloy plates grows, the strength and fracture elongation decrease, and the cupping value is greatly improved. This is mainly related to the weakening of base texture and the easy sliding of base surface.
