Abstract:

In order to further optimize the forging process of Ti-55531 titanium alloy, the influences of deformation amount on microstructure and mechanical properties were analyzed, and the microstructure of Ti-55531 titanium alloy after forging was analyzed by upsetting experiments under different deformation amounts. Then, β annealing and aging heat treatment were carried out on the samples after forging, and the tensile experiment was carried out. The results show that with the increasing of deformation amount, the volume fraction of primary α phase for Ti-55531 titanium alloy decreases gradually. After heat treatment, primary α phase disappears, and the microstructure is dominated by secondary α phase. The average strength of Ti-55531 titanium alloy gradually decreases with the increasing of deformation amount, and the plasticity gradually increases with the increasing of deformation amount. In order to avoid anisotropy, the deformation amout range should be controlled at 30%-50% combined with the enterprise production standard.
