A series of Al-Ti-C master alloys with different amounts of titanium and carbon (Al-3.5%Ti-0.5%C, Al-3.5%Ti-0.7%C and Al-5%Ti-1%C) has been developed by adding activated graphite to molten Al-Ti binary alloys. The micro-structures of the developed alloys were investigated. The efficiency of the produced alloys as aluminum grain refiner was evaluated. The effects of the following factors were investigated: addition rate of each master alloy, the pouring temperature of the refined metal and the holding time before pouring. Also, the contact time for each refiner was studied. The results were significant and the refiner Al-5%Ti-1%C was the most effective.
