The paper presents investigations on manufacturing titanium aluminide, TiAl, and iron aluminide, FeAl, by self-propagating high-temperature synthesis (SHS) combined with hot pressing (HP) or hot forging (HF). TiAl was prepared from equimolar powder mixture of titanium hydride and aluminium. FeAl was obtained directly from metal powders, the Fe/Al atomic ratio being 60:40. The SHS process was carried out in an Ar/H2 gas mixtures, using global ignition technique. Chemical and phase composition as well as morphology, density and porosity were analysed after each processing step. Selected samples were subjected to mechanical testing.
