摘要：

Al-Ti-C master alloys used as grain refiners of aluminum and its alloys with different titanium and carbon contents were prepared by excess aluminum, graphite powder and titanium dioxide in the presence of cryolite flux. The phenomenon that Al-Ti-C alloys creep up along the inner wall of the crucible when TiO2 content in the flux comparatively excess aluminum content was found. The influence of various process parameters on Al-Ti-C master alloy has been studied in detailed. Microstructure and phase structure indicate that TiC and TiAl3 are the two secondary phases, and the content of TiA(3) and TiC are depended on the TiO2 content and Ti/C mass ratio in raw materials.
