The flow properties of thermo-mechanically processed Ti-6A1-4V alloy were investigated in this study. Two samples from as received Ti-6Al-4V alloy plate with consisting coarse β grains of ∼ 170 μm size were rolled at 940°C and 550°C respectively. In hot rolled (940°C) sample fully equiaxed microstructure with average grain size ∼ 2.3 μm was produced. In warm rolled (550°C) sample, heterogeneous microstructure was produced, which consists of elongated and partially equiaxed grains. To investigate flow properties of hot and warm rolled Ti-6Al-4V alloy samples, differential strain rate tests were performed. Strain rate sensitivity (m) values and apparent activation energy (Q) for were calculated for both hot and warm rolled samples.
