摘要

本文依据铝硅合金的结晶生长

变质后硅晶体生长形貌与晶体结构的变化及变质机制需要统一的观点

以基本理论为指导综合分析了国内外与上述内容有关的论著。最后推理得出比较合理的钠变质的机制。

Abstract

In this paper

based on the viewpoint of unification ofcrystallization of Al-Si alloys

change of growth morphology and crystal-lographic structure of Si after Na modification

and modification mechanism

and guided by basic theory

investigation works on the crystallization and modification of Al-Si alloys were reviewed comprehensively. Then a comparatively reasonable Na modification mechanism was proposed.
