摘　　要：概述了含长周期堆垛有序(LPSO)相镁合金的研究现状,介绍了LPSO相的基本结构特性,包括LPSO相的精细结构、形成条件及转化关系。指出LPSO相有益于镁合金的力学性能的提高,并综述了含LPSO相镁合金的力学行为及强韧化机制。LPSO相的形成、转化问题是当前研究重点。The research status was summarized for the LPSO-phase-containing（ Long Period Stacking Ordered） magnesium alloys. The basic structural characteristics of the LPSO- phase-containing magnesium alloys were concluded, including the fine structure, formation conditions and transforming relationship. Then, we indicated that the LPSO phase could improve mechanical properties of the magnesium alloy and summarized the strengthening and toughening mechanism of LPSO-phase-containing magnesium alloy. The research should still focus on the points of formation and transforming of the LPSO phase.
