Abstract: Ti-46Al-2Cr-2Nb-(B, W)(at%) alloy prepared by powder metallurgy was direct heat treated and microstructures of the alloy were obtained by cooling at different cooling rates. Results show that duplex microstructure consisting mainly of fine equiaxed γ grains and lamellar colonies were obtained at cooling rate of 50°C/min. High volume fractions of lamellar colonies result in low elongation. Structure consisting mainly of fine γ grains and α2grains were formed at cooling rate of 10°C/min and 5°C/min. Presence of α2phase further reduced the elongation.
