摘 要: 近年来,研究发现通过适当的合金化和热处理,可在镁合金中引入长周期堆垛有序结构(LPSO),从而显著改善镁合金的加工性能和力学性能,同时,对镁合金耐腐蚀性能的提高也有益处。目前,国内外针对含LPSO相镁合金开展了大量基础研究,特别对LPSO相的结构和形成条件已有较为深入和全面的认识,但针对含LPSO相镁合金的力学性能及耐腐蚀性能的研究则相对较少。在简要总结LPSO相的结构类型与形成机理的基础之上,全面综述含LPSO相镁合金的力学性能和耐腐蚀性能的国内外研究现状,以期为新型含LPSO相镁合金的开发和性能调控提供参考。

Abstract:Recently, it is found that long-period stacking ordered (LPSO) structure can be introduced into magnesium alloys through proper alloying and heat treatment processes, which can improve the process ability and mechanical properties of magnesium alloys, obviously, and also have some positive effect on the corrosion resistance of magnesium alloys. At present, a large number of basic researches on LPSO-containing magnesium alloys have been carried out at home and abroad. Although there has been relatively deep understanding on the structure and formation behavior of the LPSO phase, there are relatively few studies on the mechanical properties and corrosion resistance of LPSO-containing magnesium alloys. After a brief summary of the structure and formation behavior of the LPSO phase, the research status of the mechanical property and corrosion resistance of LPSO-containing magnesium alloys have been comprehensively reviewed in order to provide references for the development and performance control of new type LPSO-containing magnesium alloys.

 

Key words: magnesium alloy; long-period stacking ordered structure; mechanical properties; corrosion resistance
