Silicides with transition metals such as Mo, Nb, W and Ti whose melting temperatures are around or above 2,000 C have been of great interest as the potential candidates for refractory materials operating at more than 1,500 C. Ti[sub 5]Si[sub 3] is also a potential candidate as a refractory material because of its high melting temperature (about 2,130 C), low density (4.32g/cm[sup 3]), high strength and good oxidation resistance at high temperatures. It crystallizes in a hexagonal D8[sub 8] structure. In this paper the orientation and temperature dependence of yield stress of Ti[sub 5]Si[sub 3] single crystals are presented together with the deformation mechanism using these crystals.
