Although extensive research has been made for evaluating the activation energy Q of hot deformation in microalloyed steels, almost no attempt has been made for directly comparing the influence of each element. In this study, through a series of hot compression tests of four different microalloyed steels, we have systematically explored the influences of Nb, V, Ti, and Mo on the Q and have directly compared the effect of each element in a quantitative manner.
