摘要

在试验室制出AlTi5C0 .3中间合金细化剂

该中间合金对纯铝有较好的细化作用。对Al Si合金进行细化时试验发现

较低的加入量对合金基本不起作用

当w（Ti）达 0 .15 %左右时

才能达到最佳细化效果

并且发生较早的细化衰退。Mg元素对其细化能力有促进作用

Abstract

A new Al 5Ti 0.3C master alloy refining agent is prepared in lab

which has a good refinement effect with 0.1%～ 0.2% addition on pure aluminum. Higher addition levels w （Ti）=0.15% are needed to achieve good refining effect for Al Si alloy while refinement fading occurs early. Mg can enhance the refining ability of the master alloy.
