摘要
综述了Al-Ti-B中间合金的制备方法及组织特征。分析了氟盐反应制备法的缺点,改进制备工艺和优化合金成分是改善Al-Ti-B中间合金组织形态并提高其细化性能的重要途径。探索超声场等外场作用下Al-Ti-B中间合金的制备工艺,以及开发新型Al-Ti-B-RE晶粒细化剂是Al-Ti-B中间合金的主要发展方向。
The manufacture and microstructure of Al-Ti-B master alloys are reviewed. The shortcomings of the reaction of halide salts with molten aluminum to produce Al-Ti-B master alloy are pointed out, and the improvements in the manufacture process and alloy chemistry, are believed to be the most effective way to improve beth the microstmeture and refining performance of Al-Ti-B mas- ter alloy. The manufaeture of the master alloy under the ultrasound field and development of Al-Ti-B-RE grain refiner will be among the future trends.
