In this study, isothermal compression tests at the temperature range of 1123 - 1273K and the strain rate range of 0.001 - 1s-1 were conducted to analyze the elevated temperature deformation behavior of TA7 titanium alloy for the purpose of acquiring the optimum processing parameters. Besides, a modified parallel constitutive model was put forward to illustrate the high temperature flow stress as the function of the strain rate, the deformation temperature and the true strain. Thereafter, the processing map which was on the basis of dynamic materials model was established. Thereafter, the investigation was made from the microstructure of compressed TA7 titanium alloy specimens to validate processing map. According to the result, deformation temperature of 1223K and strain rate of 0.001s-1 were the best processing parameters for the TA7 alloy. In addition, the instability regions located at relatively lower temperature-higher strain rate region.
