铸造铝合金的晶粒细化与钛硼添加剂

Graip Refining and Titaniun-boron Additive of Aluminum Casting

对铝合金熔体中加Ti细化晶粒的4种方法进行了分析，提出钛硼添加剂可以替代传统的Al－Ti中间合金，成为铝合金中Ti元素的主要添加形式，并给出了在ZL201和ZL101A合金中使用钛硼添加剂的生产试验数据及熔化操作要点。

This paper analyzes the four methods to refine the grain by adding Ti in the smelted aluminum alloy, proposes to use titanium - boron additive as the main additive with element Ti for aluminum alloy, instead of the traditional Al - Ti intermediate alloy, and gives the test data for producing ZL201 and ZL101A alloy added with titanium - boron additive and smelting operating skill.
