Popis: The hot deformation behavior of AA-FGH95 superalloy was investigated by hot compressive tests on Gleeble-1500D thermal simulation test machine in different temperatures and strain rates. The true stress-strain curves were obtained, and based on the deformation data, the constitutive equation and processing map of FGH95 superalloy were built. The deformation active energy of AA-FGH95 is Q=695.78 kJ/mol. The results show that the simulated maximum stresses are in agreement with the experimental data, and the average error is about 6%. Based on the processing map, the safety processing parameters of 1070-1100℃ and 0.01-0.001 s-1 are confirmed. When the temperature reached 1100℃, the maximum strain rate increased to 0.5 s-1.
