Abstract
TC11 titanium alloy (Ti-6Al-3Mo-1.2Zr-0.3Si) was subjected to solution treatment above β-phase field solution for 1 h with different cooling rates, such as water quenching, oil quenching, air cooling and furnace cooling, and gained four different microstructures. The relationship between microstructures and ultrasonic parameters such as ultrasonic longitudinal wave velocities (ν) and attenuation coefficients (α) was investigated. The results show that ultrasonic longitudinal velocities and attenuation coefficients increase with reducing the cooling rate from water quenching to furnace cooling. The hardness of these microstructures exhibits an opposite behavior to longitudinal wave velocity and ultrasonic attenuation coefficient.
