Abstract: The study investigates the plastic deformation of titanium alloy under moderate strain rates and warm temperature condition. The compression tests are carried out at constant strain rates of 0.01, 0.1, and 1 s-1 to the reductions of 30, 50 and 70% in height at temperatures of 25,100,200,300,400 and 500°C. The flow stress data are analyzed in terms of strain rate and temperature sensitivities. The flow stress decreases with the increase of temperature, but its variation with strain rate is low. Micro structural characteristics of Ti-6Al-4V solid material after compressive plastic deformation were studied in the temperature range 25-500 °C and at strain rates of 0.01, 0.1 and 1.0 s−1. The fracture of the material occurs at a reduction in height of 70% and shows shear banding when compressed uniaxially at strain rates above 0.01s -1 up to a temperature of 500oC
