中文摘要：

塑性差已成为变形镁合金加工与应用上的一个瓶颈，改善变形镁合金的塑性也就成为变形镁合金研究与应用中急需解决的关键技术之一。细化晶粒、控制织构、激活非基面滑移系可以显著改善镁合金的塑性，是较有前景的塑性改善方法。从以上3方面综述了变形镁合金塑性改善的最新研究进展。

英文摘要：

Poor ductility is a bottleneck of processing and application of wrought magnesium alloys,so ductility enhancement becomes a key to research and application of wrought magnesium alloys. Grain refinement, texture controlling and nonbasal slip system activation improve ductility of magnesium alloy remarkably, which are promising methods. The recent progress of ductility improvement of wrought magnesium alloys is reviewed from above three aspects.
