摘要

利用液相烧结法制备了一种Al-10SiC/Al4C3中间合金

并将其用于细化AZ63合金。X射线衍射分析结果表明

Al-10SiC/Al4C3中间合金的相组成除α-Al外

主要为Al4C3相、Si相以及未反应的SiC相。在750℃下加入0.5%的Al-10SiC/Al4C3中间合金

可以使AZ63合金的晶粒尺寸从450μm左右细化到150μm左右。当Al-10SiC/Al4C3中间合金加入量达到0.5%后

AZ63合金的晶粒尺寸不再随中间合金加入量的增加而继续减小。

Abstract

Al-10SiC/Al4C3master alloy grain refiner was prepared for the grain refinement of AZ63alloy through liquid sintering process.X-ray diffraction spectrum shows that the Al-10SiC/Al4C3master alloy is composed of primary Al phase

A14C3

Si and SiC.With 0.5% Al-10SiC/Al4C3master alloy addition at 750℃

the grain size of AZ63 magnesium alloy can be decreased from approximately 450μm to150μm.However

with Al-10SiC/Al4C3 master alloy addition more than 0.5%

refinement effects of grain size in the AZ63alloy can be ignored.
