Two types of TiAl intermetallic compound matrix composites were fabricated by the combustion synthesis. A powder mixture of titanium, aluminum, and carbon was used to synthesize in-situ a dispersed Ti<SUB>2</SUB>AlC particle composite. Theother material was a fiber reinforced composite, prepared through a pseudo-HIP process. X-ray analysis and microstructure observation were performed to evaluate the reaction products. In the Ti-Al-C system, a dual phase TiAl matrix dispersed with Ti<SUB>2</SUB>AlC particles was obtained by HIP'ing at 1473K. In the TiAl/Si-Ti-C-O fiber composite case, no interface product was detected, but when the synthesis temperature reached 1273K, the Ti<SUB>2</SUB>AlC was detected as the reactant.
