- W979244359 abstract "研究TiC和TiAl3细化工业纯铝时TiAl3的存在对TiC在铝基体中分布及α（Al）晶粒形核的影响，分析Al-Ti-C晶粒细化机制。结果表明：TiC单独作为工业纯铝的晶粒细化剂时，大量TiC被α（Al）晶粒推向树枝晶的晶界处，从而限制了TiC的异质形核作用；当TiC和TiAl3共同作为晶粒细化剂时，在α（Al）晶粒内部出现了大量TiC粒子，大量的TiC粒子成为了α（Al）的结晶核心，并且在TiC颗粒和铝基体的界面处存在“富Ti过渡区”；TiAl3在铝熔体中分解释放出Ti原子并向TiC粒子周围偏聚，形成的“TiC/铝熔体界面富Ti过渡区” 改善了TiC与α（Al）的结构适应性，降低了TiC粒子的表面张力，促进了TiC粒子在铝熔体中的均匀分布，提高了其形核能力。" @default.
