To produce TiAl intermetallic compounds, a combustion synthesis was attempted with a sintering additive of Co/Al. Mechanical properties of the combustion synthesized products were examined in the range of Ti/Al ratio from 0.43 to 2.33. The measurements of density, phases, microstructure, and size accuracy of the products revealed that a good performance with high density and fine micro structures was obtainable when the Ti/Al ratio was in the range from 1.0 to 1.22. Effect of the quantity of Co/Al additive on the density of the products was also examined.
