摘　　要：合金化和微合金化作为改善Mg-Zn-Al系镁合金组织和性能的重要工艺手段之一,目前已引起国内外的广泛关注和高度重视,并对此开展了大量的研究。综述了Mg-Zn-Al系镁合金合金化和/或微合金化的研究进展,尤其是Zn、Al、Ca、Sr、Si和RE等合金元素对合金组织和性能的影响,指出了目前还存在的问题,并对今后的发展进行了展望。Mg-Zn-Al based magnesium alloys is thought as a potential elevated temperature magnesium alloys. At present, the research and development of alloying and micro-alloying of this kind of alloys have received much attention all over the world, and consequently many researches have been carried out. In the paper, the latest research and development status of alloying and micro-alloying of the Mg-Zn-Al based elevated magnesium alloys, especially the effects of Zn, Al, Ca, Sr, Si, RE elements and so on on the microstructure and mechanical properties, are reviewed. The existing problems and the development trend of the Mg-Zn-Al based alloys are also analyzed and pointed out respectively.
