Constitutive modeling and microstructure change of Ti-6Al-4V during the hot tensile deformation

► Uniaxial tensile tests were performed on a Ti-6Al-4V alloy sheet in the hot environment. ► The Arrhenius-type equation was investigated to characterize the hot tensile deformational behavior of Ti-6Al-4V. ► The microstructure changes between the deformed specimens and the initial ones were studied in this paper.
