In this paper the effect of isothermal forging process parameters on the microstructure andthe mechanical properties of TA15 titanium alloy was researched. The results of the tests indicatethat, in the range of temperature of 850 ºC~980 ºC and deformation degree of 20%~60%, with theincrease of temperature or deformation, as the reinforcement of deformation recrystallization, theprimary α-phase tends to the spherical shape and secondary α-phase transforms from the acicularshape to fine and spherical shape with disperse distribution, which enhance the tensile properties atroom and high temperature. With the increment of forging times, the spheroidization of primaryα-phase aggrandizes and secondary α-phase transforms from spherical and acicular shape to widestrip shape, which decrease the tensile properties at room and high temperature. The preferableisothermal forging process parameters are temperature of 980 ºC, deformation degree of 60%, andfew forging times
