Abstract: PURPOSE:To easily obtain a material excellent in spreadability and toughness by charging a green compact of a powder mixture for which respective contents of impurities, such as O, C, and N, are limited and which is composed essentially of Ti and Al into a vessel having slightly larger size, performing self-burning, and then applying hot working, etc., without bringing the compact into contact with the air. CONSTITUTION:The powder mixture of Ti and Al for which the contents of O, C, N, H, and Cl as impurities are limited to <=0.14%, <=0.05%, <=0.05%, <=0.01%, and <=0.005%, respectively, is prepared. This powder mixture is subjected to pressing at ordinary temp. or to cold isostatic pressing, and the resulting green compact A having outside diameter D0 is charged into a vessel B. The vessel B has inside diameter d1 satisfying equation d1=D0+(1 to 5)mm and also has the wall thickness of <=10mm. Subsequently, the vessel B is closed with a top lid and reduced to the vacuum of 5X10<-1> to 5X10<-10>Torr, and heating is applied to allow sintering and synthesis to proceed. Then, hot isostatic pressing or hot working is applied to obtain Ti-Al based raw material.
