In this paper, tensile properties at high temperature were investigated on the sintered TiAI compacts produced by MIM process. The sintered Ti-45A1, Ti-48AI, Ti-50A1 and Ti-52A1(at.%) compacts showed the relative densities more than 95% by sintering at 13751 for.2hr in vacuum(10<SUP>-2</SUP>Pa order).<BR>The results obtained were summarized as follows:<BR>(1) The tensile strengths at 800°C for Ti-45A1, Ti-48AI and Ti-50Al compacts were almost equal to the strength at room temperature, which were in the range of 370 to 400MPa. The Ti-52Al compact showed smaller tensile strength at 800°C(330MPa) than the strength at room temperature(430MPa). The elongations at 800°C for TiAl compacts increased with increasing Al content. Especially, the Ti-52A1 compact showed the highest elongation of 13%.<BR>(2) The tensile strengths at 1000°C for all TiAI compacts were smaller(-200MPa) than the strength at 800°C, which were sligthly increased with decreasing Al content. The elongations at 1000°C were still more than 10%.
