In the study of hot forming processes the knowledge of interaction between microstructural behaviour and control process parameters such as temperature, strain rate and strain is very important. In the last decades, processing maps have been developed to design, control and optimize the hot deformation of various metallic materials. In this work, in order to study the hot formability of medium carbon microalloyed steel, during hot compression tests, a comparative study between two types of processing maps constructed using phenomenological and thermodynamic continuum criteria have been carried out. The analysis of the maps indicates that the studied steel does not undergo any type of plastic instability. However, the maps corresponding to the deformation of ε = 0,6 reveal a domain of dynamic recrystallization, considered as the more efficiently domain within the “safe” region process. This domain is centered at 1150 °C and 10 s–1. Also, the comparative study of the obtained results shows the difference between the positions of plastic deformation domains predicted by the two criteria.
