摘　　要：Fe是镁及镁合金中的有害元素。介绍了镁合金中铁相的形态及其对镁合金组织性能的影响,综述了含Mn、B、Zr、Ti等镁合金除铁剂的研究现状及消除和改善铁相形态的措施,分析了影响除铁效果的因素,指出了今后镁合金除铁的研究方向是高效并确保镁合金良好的综合性能。The corrosion resistance and mechanic al properties of magnesium alloys can be deteriorated by the harmful element Fe. Its content is strictly controlled in magnesium alloys. The forms of iron phases and their influence on the structure and properties of magnesium alloys are introduced. The present state of iron reduction containing elements of Mn,B ,Zr,Ti are summarized. Additionally,the influence factors of iron reduction are analyzed. And the development and research direction of iron reduction in future are discussed.
