摘　　要：总结含铝及不含铝镁合金的晶粒细化方法和理论模型。不含铝的镁合金主要利用含Zr中间合金细化,而对含铝镁合金的晶粒细化缺乏深入理解并易引起混淆。未来的研究应致力于细化机理,尤其要结合合金、杂质元素及形核颗粒理解细化机理。The grain refinement methods and theoretical model of magnesium alloys with and without aluminum are summarized. The master alloy containing Zr is mainly used for refining magnesium alloys without aluminum. However, it is lack of the deep understanding of grain refinement for magnesium alloys with aluminum. The future researches should focus on the understanding of grain refinement mechanism and especially take into account combination of alloy, impurity elements and nucleation particles.
