摘　　要：镁合金是最轻的金属结构材料,而合金元素的加入对改善其组织、力学性能和耐腐蚀性等,特别是高温性能具有重要作用。本文结合我国富有的稀土和碱土资源,介绍了它们在镁合金中的阻燃作用、变质作用、合金强化作用和抗腐蚀作用等的研究进展,概括了当前研究中存在的问题,提出了今后的研究方向。Magnesium alloys are the lightest metallic structural materials. When some kinds of alloy element are added, their properties, i.e. microstructures, mechanical properties, and corrosion resistance, are improved, especially on high temperature properties. China is rich in rare earth and alkaline earth elements. In this paper, the latest research and development status of effects of rare earth and alkaline earth elements on heat resistance, modification behavior, alloying strengthening, and corrosion resistance of magnesium alloys were introduced. The existed problems and the development trends were analyzed and the research fields were also pointed out in the future.
