The high temperature hot deformation behavior of TB17 titanium alloy was studied using Gleeble-3800 thermo-compression simulation tester at the temperature of 860 -980 ℃, strain rate of 0.001-1 s–1 and the deformation degree of 0.7. The deformation behavior and microstructure were studied. By building the relationship between material parameters and true strain, the relationship between flow stress and deformation temperature, strain rate and strain was established by using Arrhenious constitutive equation and Z parameter. The results show that TB17 titanium alloy is more likely to happen continuous dynamic recrystallization at strain rate of 0.001-0.01 s–1 and deformation temperature of 890-980 ℃, while discontinuous dynamic recrystallization occur mainly at high strain rate (≥ 0.1 s–1). The error analysis shows that the average relative error between calculated and measured values is 6%. It indicates that the constitutive relation model has higher accuracy.
