摘要：
The hot deformation behavior of 0Cr17Mn17Mo3NiN austenitic stainless steel is investigated by Gleeble-3500 in the temperatures range of 950-1 100℃ and strain rates range of 0.01-1 s-1. The constitutive equation of this stainless steel under hot deformation is determined according to the true strain-true stress curves. The processing map is established on the basis of the dynamic material model (DMM). The results show that the flow stress decreases with the increase of the temperature at the same strain rate; however, the flow stress decreases with decrease of the strain rate at the same temperature. The activation energy of hot deformation for the austenitic stainless steel is 549 kJ/mol. The energy dissipation efficiency is 0.28-0.3 in the temperature of 980-1 050℃, when the true strain is 0.4 and the the strain rate is 0.01-0.1 s-1. The optimized hot deformation processing window of the austenitic stainless steel is identified as 980-1 050℃, 0.01-0.1 s-1, in which the dynamic recrystallization in the stainless steel is easily occurred. © 2017 Journal of Mechanical Engineering.
