The flow curves of the steels exhibit the classic softening due to dynamic recrystallization. The characteristic pairs of stress-strain values (zero, critical, peak, saturation, and steady state) were determined by the analysis of the work hardening curves. These values were analyzed by applying first the classical Sellars and McTegart approach. Once the apparent stress exponents and activation energies were determined as being in the vicinity of 5 and above 270 kJ/mol, respectively, a modified hyperbolic sine equation was used. The flow curves were characterized by work hardening, dynamic recovery, and recrystallization terms at any processing conditions, showing a direct relationship with the silicon content of the steels. Finally, all the flow curves of studied steels were discussed and modeled as a function of the processing parameters and silicon content.Peer Reviewed20192019-10-0120202020-02-07journal articlehttp://purl.org/coar/resource_type/c_6501VoRhttp://purl.org/coar/version/c_970fb48d4fbd8a85info:eu-repo/semantics/articleapplication/pdfhttps://hdl.handle.net/2117/177212https://dx.doi.org/10.1520/MPC20190026reponame:UPCommons.
