摘要

Mg-Al系镁合金是有发展前途的低成本镁合金，利用合金化和微合金化改性Mg-Al系镁合金得到重视。综述了稀土元素在Mg-Al系镁合金中的作用及研究现状，重点分析了轻稀土元素(La、Ce、Pr、Nd和Sm)、重稀土元素(Y、Gd、Dy、Ho、Er、Yb和Lu)和Sc元素对Mg-Al系镁合金显微组织、力学性能和耐蚀性能的影响，并指出了稀土元素改性Mg-Al系镁合金存在的问题及未来的发展方向。

Abstract

Mg-Al series alloys belong to potential magnesium alloys with low-cost. The modification of Mg-Al series alloys by alloying and micro-alloying is paid attention. The role and research status of rare earth elements in Mg-Al based alloys were reviewed

especially the effects of light rare earth elements（La

Nd and Sm）

heavy rare earth elements（Y

Yb and Lu） and Sc elements on the microstructure

mechanical properties and corrosion resistance of Mg-Al series alloys

and the existing problems and future development about the modification of Mg-Al series alloys by rare earth elements were also pointed out.
