Conclusions 1. During continuous heating of steel at a rate of about 100°K/min the intensity of development of transformation in the intercritical temperature interval changes nomonotonically. At certain temperatures we find minimal intensity of austenite formation. The degree of lowering of the intensity of transformation and the effect of the temperature corresponding to this depend to a considerable extent on the grain size. 2. The complex nature of the change in intensity of transformation in dependence on the temperature is due to the difference between the processes occurring in different temperature intervals (the simultaneous nucleation of centers of γ-phase and their growth or only growth), the change of the mechanism of diffusion of carbon (from surface diffusion to bulk diffusion), and to the thermodynamic determination of the acceleration of transformation of low carbon ferrite into austenite at high temperatures.
