Microstructure evolution and mechanical behavior of alpha/beta Ti-6Al-4V titanium alloy with initial α-colony microstructure during uniaxial compression at 600 and 800°C to a height strain of 70% were studied. It was shown that decrease in deformation temperature considerably influences on the kinetics of globularization of a lamellar microstructure. At the lower temperature stages of strengthening and softening extend that associates with inhibition of globularization. Deformation at 600°C is also associated with a smaller fraction of high-angle boundaries during deformation, smaller fraction of globular grains, increased contribution of shear deformation and more intensive rotation of α-lamellae towards the metal flow direction. In contrast to 800°C, the rate of thinning of α-lamellae at the lower temperature is noticeably higher. The results obtained are related to the change of the type of dislocation slip in α-lamellae due to inhibition of dynamic recovery with decreasing deformation temperature.
