【 摘 要 】

The uniform grain structure of titanium alloys is required to enhance the product manufacturability and precision. For the research, flat blanks cut out of the BT-22 titanium alloy forged bar were used. Bending tests with the subsequent annealing were carried out at the temperature of 800°C during 1-5 h. The grain size change and its uniformity depending on the annealing duration were analysed. The possibility of obtaining the uniform fine-grained structure after deformation and annealing for 4 hours was established.
