Abstract The hot deformation behavior of the heat resistant steel T122 was investigated with a compression test on Gleeble 3500 simulator at a temperature range of 900--1200 ℃ and strain rate range of 10 -2—10 1 s -1. A method was developed to determine the activation energy and material parameters in the hyperbolic sine constitutive equation. The activation energies determined are 570 kJ/mol and 548 kJ/mol for steel T122 in saturation stress and peak stress, respectively. The values of critical strain for dynamic recrystallization (DRX) initiation was determined from the strain-stress curves, a equation related to the Zener-Hollomon parameter was obtained.

Key words: heat resistant steel T122 hot deformation hyperbolic sine constitutive equation
