Al-Ti-C alloys of various compositions have already been commercialized as grain refining master alloys and have long been in use in aluminium foundries world wide. The present work was undertaken to investigate the possibility of manufacturing Al-TiCp grain refiner master alloy tablets by the mechanical alloying route. Carbon was mechanically alloyed into Al-Ti alloy powder grains via high energy ball milling. The Al-Ti/C powder blend thus obtained was heat treated to promote the precipitation of TiC. Al4C3 was the first phase to form inside the powder grains upon thermal exposure. The Al4C3 particles which were too small to be identified with the optical microscope until 750°C, have grown until 850°C where they have started to react with Al3Ti to produce TiC. A very fine dispersion of TiC particles was thus generated inside the powder particles while the Al3Ti phase has almost vanished.
