摘要

通过对Ag Cu合金熔体的过热处理

研究了不同生长速率时的平界面的结晶位向

发现高的熔体温度使平面单晶的位向产生分支现象。应用Leonard Jones势能和团簇概念分析了位向分支的形成原因

表明团簇状态在母相中的分布对结晶取向具有重要作用。

Abstract

Effects of the Ag-1Cu melt super-heat treatment on crystallization orientation in plane interface at various growth rates are investigated. It is found that the melt at high super-heated temperature is responsible for the branching to orientation of plane single crystal. The formation mechanism of orientation branching is analyzed by Leonard-Jones potential energy and cluster theory. It is showed that the distribution of cluster in primary phase plays important role for crystallization orientation.
