Abstract

Hot deformation behavior of S32760 super austenitic stainless steel was studied in the temperature range of 950 ∼ 1250 °C and strain rate range of 0.1∼10 s-1 employing Gleeble 3800 equipment. The flow stress was modeled using Arrhenius equation and Zener-Hollomon parameter(Z). The microstructures of the specimens under various conditions were investigated, and dynamic recrystallization of austenite, dynamic recovery of ferrite and phase contents varied with temperature and strain rate. The difference of flow stress between experiment and constitutive equation was explained by the phase contents. Finite element analysis was performed to calculate forging load under the same conditions of compression test using modeled flow stress. It was validated that forging load can be predicted precisely with Arrhenius equation.
