Abstract: Abstract: It is known that the thermomechanical processing is one of the most important techniques for improving quality and mechanical properties of microalloyed steels. In this paper, the main parameters of hot forging (preheat temperature, strain and post-forging cooling rate) on the primary austenite grain size of vanadium microalloyed steel (30MSV6) were studied. From this investigation, it was found that increasing preheat temperature from 1150°C to 1300°C will result in a decrease in grain size number. Furthermore, it has shown that as the strain increases, the austenite grain size number increases, as is evident for the two cooling rates of 2.5°C/s and 1.5°C/s for primary austenite. Finally, it can be concluded that a verity of microstructures in microalloyed steels can be obtained depending on the deformation temperature and cooling rate. [Copyright &y& Elsevier]
