Abstract: Hot compression tests were carried out on Ti-10V-2Cr-3Al titanium alloy at the strain rate of 0.1-0.001 s^-1 and deformation temperature of 730-880 ℃, and the hot deformation behavior and microstructure of the alloy were studied. The exponential equation and hyperbolic sine equation in the phenomenological Arrhenius equation were used to describe the relationship between flow stresses and deformation temperatures and strain rates. The constitutive equation corrected by strain compensation was established and verified. The results show that the true stress of the alloy increased with increasing strain rate or decreasing deformation temperature under test conditions. At the strain rate of 0.01 s^-1, spherical and short rod-like α phases appeared in the test alloy after compression in the α+β phase region (730, 790 ℃), and the softening mechanism was dynamic spheroidization and dynamic recrystallization; recrystallized β grains appeared after compression in the β phase region (820, 880 ℃), and the softening mechanism was dynamic recrystallization. When the strain rate was in the range of 0.1-0.05 s^-1 and 0.01-0.001 s^-1, the flow behavior of the test alloy could be described by the corrected exponential equation and the corrected hyperbolic sine equation, respectively. The average relative error between the predicted flow stresses and the experimental flow stresses was 5.36%, indicating that the corrected equations had good predictive ability.
