The reaction characteristics of Ti-Al intermetallic compounds were studied, using SHS method which sustains the reaction spontaneously, utilizing the heat generated by the exothermic reaction itself. This reaction was greater affected by the chemical and physical properties of Al than those of Ti. When the TiAl, TiAl₃ and Ti₃Al synthetic reactions were carried out under the condition of lower heating rate(5℃/min), the reaction products were multi-phase because of the gravity segregation phenomenon, but reaction products under the condition of higher heating rate(50℃/min) were single phase. Also, the product density was high in the Ti₃Al reaction contained the small amount of Al. Higher heating rates resulted in a product of higher density fort the TiA1₃ reaction contained a large amount of Al. In the synthetic reaction of Ti₃Al, the Ti₃Al product increased with increasing relative green density, and was rich in the case of enveloping the compact with a insulator.
