Hot Deformation of Martensitic and Supermartensitic Stainless Steels

Abstract:

The deformation behavior of supermartensitic and martensitic stainless steels was investigated through compression test using Gleeble-3800 thermo-mechanical simulator within the temperature range of 900 – 1200 ^оС and the strain rates range of 0.01 – 10 s^-1. The results showed that the flow stress and the peak strain increase with the drop in the deformation temperature and the rise in the strain rate. Flow stress of SMS steel exceeds flow stress of MS steel for same regimes of deformation. The difference in flow stress increases with the increase in Zener-Hollomon parameter, but does not exceed 15 MPa. The critical deformation, required to start dynamic recrystallization, for supermartensitic stainless steel is slightly lower than for martensitic stainless steel. The hot deformation activation energy of steels is also investigated, their values are similar and equal to 432 and 440 kJ/mol for MS and SMS steel, respectively.
