The effect of scattering of the grain size of initial austenite on the kinetics of the γ → α transformation is analyzed for plain carbon and chromium-bearing two-phase steels. Components of a computer model describing the kinetics of the transformation, which are directly related to the size of the austenite grains, are considered. The structural parameters computed by the model and determined experimentally are compared.
