Al-Ti-C refiner has become one of the hot spots in the current casting field because it can effectively refine the structure and improve the mechanical properties of materials during the casting process. The aim of this study is to optimize the preparation process of Al-Ti-C refiner, and to further improve its application value in the field of casting through preliminary study of macrostructure and dynamics.In terms of preparation process, this study will try to use the liquid-phase reduction-solidification method to prepare Al-Ti-C refiner, and optimize the reaction temp...
