摘　　要：钪作为一种在铝合金中已得到广泛应用的稀土元素,在镁合金中的应用正引起国内外的关注和重视。综述了含Sc镁基合金的研究现状及最新进展,尤其是微量Sc对镁合金组织和性能的影响以及新型含Sc镁合金的研究开发现状,指出了目前存在的问题,并展望今后的发展。The application of scandium which has widely been applied in aluminum alloys, to magnesium alloys has been receiving much attention all over the world. In this paper, the latest research and development status of the magnesium alloys containing Sc, especially the effects of trace Sc on the microstructure and properties of magnesium alloys, the development of new type Sc-containing magnesium based, alloys, were reviewed. The existing problems and the developing trend of the alloys were also analyzed and pointed out, respectively.
