摘　　要：Al-Ti-C中间合金是一种新型铝合金晶粒细化剂,有着广阔的应用前景。综述了Al-Ti-C中间合金制备工艺的发展历程,分别介绍了熔体反应法、高温自蔓延法和热爆法工艺的特点和研究情况;简述了有关Al-Ti-C中间合金的细化机制和TiC粒子的热力学稳定性问题的争议;最后,提出了今后一段时间内Al-Ti-C中间合金领域内的发展方向。Al-Ti-C master alloy is a new type of grain refiner and has a great potential in industry applications. The development of the Al-Ti-C master alloy was summarized, and the peculiarity of three preparation methods, that is melting reaction, self-propagating high-temperature synthesis and thermal explosion, are introduced respectively. Meanwhile, the disputes in refinement mechanism and the thermodynamic stability of TiC particles are discussed. Finally, the research direction of Al-Ti-C master alloy in the future is suggested.
