Abstract

A recently modified solute drag model, taking into account the interfacial segregation of alloy elements, is applied to the decomposition of austenite into ferrite in Fe-Mo-C alloys. The calculations are carried out with assessed thermodynamic and kinetic data stored in databases. The effect of the Gibbs energy of segregation is discussed in connection with published experimental observations of the bay in the time-temperature-transformation (TTT) curve for initiation of transformation. The solute draglike effect suggested in the literature is discussed in comparison with the present quantitative calculation.
