Abstract

Self-propagating high-temperature synthesis (SHS) was used for the preparation of Al-Ti grain refiner. Al/Ti mole ratio in initial powder mixture was varied from 0:1 to 4.5:1 for controlling adiabatic temperature, which was found to have effect on the morphology and composition of synthesised Al₃Ti particles. The increase in Al powder content resulted in the adiabatic temperature rise and change of titanium aluminide morphology from needle-like to blocky.
