Influence of Isothermal Forging Temperature on Microstructure and Mechanical Properties of Ti-6Al-2Sn-2Zr-3Mo-lCr-2Nb-Si Titanium Alloy

摘要：

The influence of isothermal forging temperature on microstructure and mechanical properties of the Ti6Al-2Sn-2Zr-3Mo-1Cr-2Nb-Si alloy was investigated with the constant strain rate of 1×10-2s-1 and deformation degree of 60％. The results indicate that the microstructure is mainly made up of coarse original β grains at all temperatures, and a slight of fine equiaxed a phases exist in the microstructure only forged below the transus. The basketweave α lath distributed throughout the original β grains uniformly. The mechanical properties of TC21 titanium alloy are not sensitive to the forging temperature. Compared to other temperatures, the combination property was optimized when forged at 970℃ slightly.
