摘要	Microstructure and texture of titanium alloy are determined by thermomechanical and heat treatments and can significantly affect the mechanical properties of the final products. In this work, the microstructure and texture evolution during the heat treatment in alpha/beta and beta phase field in Ti60 precision forging bars were investigated. The results implied that the actual deformation temperature gradually decreased during precision forging processes. The microstructure and texture of Ti60 bar were determined by the finish forging temperature and the diameter, and strong microtexture macrozones existed in the forged Ti60 bar. For the bar with diameter of 45 mm (D45), the finish forging temperature fell in the lower temperature region of the alpha/beta phase field, and the main a textures in these bars were <0001> and <10<(1)over bar>0> fiber texture components in initial Ti60 bar. The similarity of the microstructure and texture were found after heat treatment at 950 degrees C. The intensity of <10<(1)over bar>0> fiber texture gradually decreased while that of <0001> fiber texture increased with the increase of the heat treatment temperature. Heat treatments have little influence on the strength of forged Ti60 bars of D45, while their ductility was reduced after beta heat treatment. For the bar with diameter of 30 mm (D30), the finish forging temperature was below the a alpha/beta phase field, and the main a texture in those bars was <10<(1)over bar>0> fiber texture component. The intensity of <0001> fiber texture in those bars increased while that of <10<(1)over bar>0> fiber texture gradually decreased with the increase of the heat treatment temperature. Their room temperature strength significantly increased with the increase of the heat treatment temperature, and yield strength and tensile strength reached to 1086 and 1144 MPa, respectively, but the elongation only 3.3% after beta heat treatment.
