Popis: The compression deformation behavior and constitutive relation of Hastelloy X superalloy were investigated in the temperature range of 950 °C to 1150 °C and strain rate range of 0.001 s-1 to 1 s-1 on a Gleeble-3500 thermo-simulation machine. The obtained experimental stress-strain data were used to establish strain-dependent constitutive equations. The correlation between the strain-dependent constitutive parameters and flow behavior was analyzed. Comparisons between the experimental and predicted results showed that the developed constitutive equation could be used to simulate numerically the flow stresses of Hastelloy X superalloy at any strains under hot deformation.
