铝及其合金的晶粒细化处理简述

A Brief Review of Al and Al Alloy Grain Refinement

介绍了用钛和硼细化铝及其合金晶粒现象，对一些有名的细化理论如“色晶反应”、“晶粒增殖”、“抑制α（Ａｌ）晶粒生长”及最新的“超形核”进行了讨论，但迄今尚无一种正确的理论能解释所有的细化晶粒现象。

The phenomena of Al and Al alloy grain refinement by Ti and B were introduced. Several famous theories, such as “Peritectic Reaction”, “Crystal Multiplication”, “Retarcl of α(Al) Crystal Growth”, and a new theory called “Super nucleation” were discussed briefly. Up to now, however, none theory could completely explain all of the phenomenona of grain refinement.
