摘　　要：利用自蔓延高温合成了Al-Ti-C晶粒细化剂,并通过金相显微镜分析了其组织.结果表明:SHS反应的主要能量来自于Ti(s) +3Al(l) =Al3Ti(s)的合成反应,镁以块状和粉状按比例加入且含量控制在1%时组织最佳。Al-Ti-C grain refiner was prepared by self-propagating high-temperature synthesis technique. Metallic phase microscope was used to examine the microstructure. The heat of self-propagating high-temperature synthesis technique mainly come from Ti(s)+3Al(l)=Al_3Ti(s).The fine microstructure was produced when the quality of Mg was 1%. Mg was put in by powder and block proportionally.

关 键 词：SHS技术 AL-TI-C晶粒细化剂 镁
