摘要

采用铝业协会制订的ＴＰ－１型标准测试法，对Ａ１－１０ＲＥ、Ａ１－５Ｔｉ－１Ｂ、Ａ１－５Ｔｉ－１Ｂ－１０ＲＥ等中间合金对Ａ３５６．２合金的细化效果进行评价，以优化铝合金轮毂制造过程中合金熔体细化处理工艺。结果表明，Ａ１－５Ｔｉ－１Ｂ－１０ＲＥ中间合金中的ＲＥ不仅可以有效抑制晶粒尺寸的衰退，而且在一定程度上改善Ｔｉ、Ｂ、Ｓｒ对Ａ３５６．２合金显微组织的细化和变质效果；ＴＰ－１型晶粒度检测法是一种简单、直观、准确的中间合金细化效果在线评价方法。

Abstract

With the calibrated aluminum association TP-1 standard test procedure

refining effects of Al-10RE

Al-5Ti-1B and Al-5Ti-1B-10RE master alloy on A356. 2 alloy were evaluated to optimize the refining process of alloy molten in aluminum alloy wheels manufacture. It is showed that RE elements in Al-5Ti-1B-10RE master alloy can not only prevent grain size from fading effectively

but also improve the refining and modifying effects of Ti

Sr on microstructure of A356. 2 alloy to some extent. TP-l standard procedure is a kind of simple

visual and exact on line method to evaluate the refining effects of master alloys.
