Al-Ti-B中间合金的遗传性研究与推广应用
Hereditary Study and Application of Al-Ti-B MasterAlloy
【摘要】 l Ti B中间合金是一种高效实用的铝合金晶粒细化剂。本文指出了Al Ti B的潜力、不足和发展趋势。概述了Al Ti B结构遗传的化学和物理基础及影响因素 ,Al Ti B细化行为的结构遗传效应 ,TiAl3 在铝熔体结构遗传中的动力学行为 ,α Al的形核机制。提出了新的Al Ti B制备技术和微细化处理工艺。认为随着Al Ti B质量的不断改进 ,尤其是高效洁净稳定型Al Ti B的出现 ,Al Ti B在细化剂市场上的主导地位将不断巩固
