Abstract

A type of Mg-Al-C master alloy for grain refinement on Mg-Al based alloys was fabricated by a special powder metallurgy method. In the master alloy, Al（C） solid solution is located at the boundaries of magnesium particles. Grain refinement experiments reveal that the master alloy can refine AZ31 （Mg-3%Al-1%Zn） efficiently. With addition of 3wt.% Mg-Al-C master alloy, the grain size of AZ31 was decreased from 850 μm to 260 μm. The mechanism on grain refinement of AZ31 magnesium alloy by the Mg-Al-C master alloy was discussed.

摘要

通过特种粉末冶金法制备了一种用于Mg-Al系合金晶粒细化的Mg-Al-C中间合金。在该中间合金中

Al（C）固溶体分布在镁颗粒的界面上。试验表明

该中间合金对AZ31（Mg-3Al-1Zn）合金有良好的细化作用。当加入3%中间合金时

AZ31的晶粒尺寸由原来的850μm减小到260μm。初步分析了Mg-Al-C中间合金对AZ31镁合金的细化机理。
