摘    要:锶作为一种应用潜力较大的镁合金合金化元素,已在镁合金中的应用研究领域引起国内外的广泛关注和高度重视。国内外近几年来的研究工作主要集中在锶对镁合金晶粒细化、第二相改性和含锶耐热镁合金的发展等方面。对国内外含锶镁合金研究工作的最新进展进行综述,介绍重庆大学近几年在含锶镁合金方面的最新研究成果,讨论若干新型含锶镁合金的组织和性能,分析含锶镁合金发展和生产应用中存在的问题和今后的研究方向。

Abstract:

Sr is a very potential alloying and/or micro-alloying element for magnesium alloys. The investigations about the effects of Sr addition on the microstructure and properties of magnesium alloys and the development of new type Sr-containing magnesium alloys have attracted an increasing interest. Recently, the work was focused on the grain refinement and the improvement of second phases in magnesium alloys by addition of strontium. The latest research status about the effects of Sr addition on the microstructure of magnesium alloys and the development of new type magnesium alloys containing Sr were reviewed, and the existing problems were discussed. The research work shows that the microstructure and composition of the master alloys containing Sr have obvious influence on the grain refinement of magnesium alloys caused by addition of strontium.
