Abstract

Abstract: Thermal compression test of Inconel625 alloy with deformation temperature of 950-1200 ℃ and strain rate of 0.001-10 s^-1 was carried out by Gleeble-3800 thermal simulation testing machine. The hot deformation behavior and microstructure evolution under different deformation conditions were analyzed. The hot processing map of the Inconel625 alloy was constructed. The results show that the flow stress of the Inconel625 alloy increases with the increase of strain rate and the decrease of deformation temperature. The higher the deformation temperature and the lower the compression strain rate, the more prone to dynamic recrystallization. The optimum hot processing parameters of the Inconel625 alloy are as follows: deformation temperature of 1010-1050 ℃, strain rate of 0.01-0.13 s^-1.
