The rates of growth of pearlite and thermodynamic quantities in commercial medium plane carbon steel and medium carbon, 0.25% chromium steel have been measured as a function of the reaction temperature.
These data have been correlated in terms of the rate equation derived by Frye et al. with an application of the absolute rate theory.
Activation energies for the growth of pearlite are reported to be 63000 cal/mol for the carbon steel and 64000 cal/mol for the chromium steel, from which it is evident that diffusion of carbon is not a rate-determining mechanism.
