摘　　要：以自行铸造的ZM5型镁合金为基,添加多种变质剂C,C2Cl6,FeCl3,TiO2等,以细化镁合金晶粒,并比较其细化效果.实验结果表明,以上变质剂均能显著细化晶粒,且细小等轴的晶粒组织可以改善其力学性能.其中,C2Cl6的细化效果最为明显.Different grain refiners such as C, C2Cl6, and TiO2 were put into the casted ZM5 magnesium alloys in order to refine the alloys and to compare the refinement effect. The result shows that all the above mentioned refiners can refine grains effectively, among which, C2Cl6 has the best refinement effect. And the fine equiaxed crystal structure of magnesium alloy may improve the mechanical property of the alloys.
