Abstract The flow curves are obtained using single-hit and double-hit hot compression tests carried out on Gleeble-3500 thermomechanical simulator. The change of dislocation density during inter-pass is related to the static recrystallization volume fraction, which can be seen as a function of time. Based on the inverse analysis of the flow curves, a new method to estimate the kinetics for static recrystallization is proposed. Conventional approach using image analyses of quenched microstructure to evaluate the kinetics for static recrystallization can be replaced from this method. The proposed method is applied to the hot compression tests of plain carbon steel, and the kinetics for static recrystallization are obtained successfully for some range of deformation at elevated temperature. The results are clarified by comparing them with that reported in the literature. It is confirmed that the proposed method could provide accurate kinetics for static recrystallization with shorter time for experiment and computation.
