摘要：

The synthesis of Al-3Ti-0.75C master alloy grain refiner was carried out by adding K2TiF6 and graphite powder together in aluminium melt from 800 to 1200 degrees C. The reaction between the halide salts and graphite in aluminium melt was also carried out at different time intervals at 1200 degrees C. The in situ formation of TiC particles in the Al/K2TiF6/graphite system involved the formation of Al3Ti followed by formation of TiC at varying temperature and time. It is observed that TiC and Al3Ti phases together showed the best grain refining efficiency in comparison to only by TiC or Al3Ti alone.
