Abstract: The phase equilibrium relationships and compositions of α2 (α)/γin the Ti-Al-Nb ternary system between 1 000～1 300℃ have been measured using diffusion couple and EPMA method. The partial isothermal sections of the Ti-Al-Nb ternary system with Nb content less than 10.0% (mole fraction) and partial vertical diagram of the Ti Al binary system have been drawn. The results confirmed the change rule of α2 (α)+γdual phase field with temperature, Nb content and the distribution ratio of Nb element in α2 (α) andγphases.
