摘要:The effects of solution temperature and aging temperature on microstructure of a new metastable β titanium alloy were studied. With the decrease of solution temperature, β grain size gradually decreased. When the solution temperature dropped to 780°C, the average grain size was about 10 μm. As the aging temperature increased from 500°C to 560°C, the secondary α phase increased. The nucleation of the secondary α phase within the grain was uniform, and its relationship with the β matrix was satisfied with Burgers. With the extension of aging time, the amount of the secondary α phases increased obviously, and they had a staggered arrangement with each other, presenting the phenomenon of the tensile strength increasing continuously. The strength level reached to 1500 MPa after aging at 500°C for 8 h.
