The strain change during the tempering of S45C martensitic steel was examined at different heating rates using a dilatometer. Tempering stages 1 and 3 corresponding to the precipitations of transition carbide and cementite were observed. Tempering kinetics at each stage was investigated from the relation between the measured strain and atomic volume change during tempering. From the tempering kinetic data, continuous heating tempering diagram was constructed and the tempering kinetic model was proposed as Zener-Hillert type differential equation.
