AbstractAbstractAn experimental study has been made of the mechanism of tempering of extra-low carbon martensitic steels. This mechanism presents several interesting features but perhaps the most important is the recrystallization that starts at about 550°C and constitutes the final stage of softening. This paper presents isothermal recrystallization curves for 0.03 and 0.021 per cent C steels at various tempering temperatures following the martensitic transformation. The effects of purity and temperature on the rates of growth and recrystallization have been studied and the energies of activation for these processes are given.
