摘要
Abstract
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 deform-ation 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 av-erage error is about 6%. Based on the processing map, the safety processing parameters of 1070-1100℃ and 0. 01-0. 001 s-1 are con-firmed. When the temperature reached 1100 ℃, the maximum strain rate increased to 0. 5 s-1 .关键词
