Abstract：

Based on the summary of the forging technical characteristics and forging technical methods of titanium alloy, the influences of the forging temperature, deformation degree and strain rate on the microstructure of TC6 titanium alloy and the influences of forging parameters on the mechanical properties of forging were discussed, and the shape characteristics, dimension accuracy and requirements of mechanical properties of TC6 titanium alloy blade with damping were analyzed. Then, its precision forging process and auxiliary processes were focused in detail, and the tensile properties at room temperature and 400 ℃ as well as the endurance properties for 100 h at 400 ℃ of TC6 titanium alloy blade with damping were tested. The research results show that the titanium alloy forging with high dimension accuracy is successfully manufactured by the above precision forging process, and the mechanical properties of titanium alloy forging is greatly increased. Thus, the above precision forging process is widely worthy to apply in engineering.
