摘    要:介绍了耐热镁合金的研究现状。Cu,Ca,Sc,Sr和稀土元素合金化可以改善镁合金的耐热性能。合金化、挤压和半固态加工等热塑性变形技术能促使镁晶胞中的棱柱面(1010^-)和棱锥面(1011^-)参与滑移,提高该类镁合金的力学性能。超塑成型技术是制备高性能耐热镁合金部件的有效途径

关 键 词:耐热镁合金  合金化  变形行为

Abstract:The research and development of heat resistant Mg alloys were reviewed and alloying these alloys was mentioned as the basic method improving the properties as well as Cu, Ca, Sc and Sr, rare-earth elements. Alloying, extrusion and semi-solid process were highlighted to introduce the sliping of prismatic plane (1010) and pyramidal plane (1011) which can benefit the mechanical properties. Superplastic process was the effective method to fabricate the heat resistant Mg alloys parts.
Keywords:heat resistant Mg alloys  alloying  deformation behaviors
