THE PLASTIC DEFORMATION BEHAVIOR OF TiAI BASED ALLOYS

Kawabate et al. show that the yield strength of TiAl binary compound increases with increasing temperature, the unusual positive stress-temperature dependence(defined as R effect below)is found by compression experiments on Ti-57 at ％ Al single crystals. But the result of Lipisitt et al. and Huang shows that the tensile yield strength of TiAl binary
