Abstract

The hot deformation behavior of Ti-6Al-4V alloy was investigated by isothermal compression tests carried out in the 1083–1173 K temperature range and 0.01–10 s⁻¹ strain rate regime. The effect of temperature and strain rate on the flow stress of this alloy was evaluated, and, the constitutive equation was obtained, which could well predict the flow stress. Furthermore, the microstructure evolution was investigated, it was also found that the elongated primary α and secondary α grains became equiaxed through suitable treatment, where the deformation mechanism was dynamic recrystallization.
