变质剂对镁合金晶粒细化的实验研究

Research on Grain Refinement of Modification Agent on Magnesium Alloy

通过添加变质剂,研究ZM5型镁合金的晶粒细化机理。实验结果表明:C、C2Cl6、FeCl3、TiO2、Ca都能细化ZM5型铸造镁合金。但是细化效果最好的是C2Cl6,细化晶粒后其力学性能也得到了改善。

The grain refinement mechanism of ZM5 magnesium alloy was researched by adding modifier. The results show that the modification agents of C, C2Cl6, FeCl3, TiO2 and Ca can refine ZM5 casting magnesium alloys. But the best refinement effect is adding C2Cl6, and the mechanical performances have also been improved after grain refinement.
