Mechanically Activated Combustion Synthesis of Titanium Aluminide

Titanium aluminide compound was synthesized by the thermal explosion mode of selfpropagating high-temperature synthesis (SHS). Considering to ignition temperature of TiAlwhich was obtained about 800ºC, three different temperature and three activation times of initial powder mixture were chosen. The maximum combustion temperature was determined to be about65%, but it was not remarkably affected by the milling time. The time-to-ignition was found to behighly influenced by milling time. The products were characterized by X-ray diffraction and it was found out that the products were consisted of the TiAl phase with Ti3Al as second phase
