摘要

研究了新近开发的Ａｌ－Ｔｉ－Ｃ－Ｂ中间合金细化剂，检查了其显微组织及细化工业纯铝及含Ｚｒ铝合金的性能，并与Ａｌ－Ｔｉ－Ｂ中间合金细化剂进行了对比。结果表明：Ａｌ－Ｔｉ－Ｃ－Ｂ中间合金细化剂含有Ａｌ３Ｔｉ、ＴｉＢ２和ＴｉＣ三种第二相，它们形成尺寸细小弥散分布的多相粒子团，其细化工业纯铝晶粒的能力明显优于Ａｌ－Ｔｉ－Ｂ中间合金细化剂，并克服了Ａｌ－Ｔｉ－Ｂ中间合金细化剂易被Ｚｒ原子毒化的弱点。分析认为，Ａｌ－Ｔｉ－Ｃ－Ｂ中间合金优异的细化性能归功于多相粒子团表面凹陷处的物理化学作用

Abstract

The present work has studied the recently developed Al Ti C B master alloy. Its microstructure and ability to grain refinement of commercial pure Al and Zr containing Al alloy were examined and compared with those of Al Ti B master alloy. The results show that there are Al 3Ti、 TiC and TiB 2 phases in Al Ti C B master alloy

which form small size、 dispersed multi phase clusters; the grain refining ability of Al Ti C B master alloy is superior to that of Al Ti B master alloy; It overcomes the shortcoming of Al Ti B master alloy poisoned by Zr atoms. It is thought that the excellent grain refining properties are attributed to the physical and chemical role of holes of multi phase clusters′ sufaces.
