Abstract Aiming at acquiring the best processing parameter of extruded FGH4096 superalloy in plastic hot working, high temperature compression experiments of hot extruded FGH4096 superalloy were carried out on thermal simulation test machine Gleeble 3180D. The high temperature deformation behavior of extruded FGH4096 superalloy under the deformation temperature of 1 020 ℃ to 1 140 ℃, the strain rate of 0.001 s^-1 to 1.0 s^-1, and the compression reduction of 50% was investigated. Furthermore, the impact of the strain rate and deformation temperature on flow stress was analyzed and the related constitutive equations and hot processing map based on hyperbolic sinusoidal model and dynamic material model were constructed. The results indicated that the extruded FGH4096 superalloy was endowed with a thermal deformation activation energy of 1 128.79 kJ/mol. The optimal hot processing parameters lay in the deformation temperature of 1 049—1 080 ℃ and the strain rate of 0.005—0.013 s^-1, respectively. In the optimal parameters, the peak energy dissipation rate was 64% and the complete dynamic recrystallization with fine and uniform grains was found by microstructure analysis.
