Abstract Both regular solution and supper-component models were used to calculatethe driving force for isothermal transformation of Fe-C-Si-Mn alloys. The relativenucleation rate and incubation period were estimated based on the calculated driving force.The results suggest that for carbon-free alloys, the incubation is principally determined by thedriving force, while for carbon-contained alloys, the driving force is not the dominant factor.The result is considered to be in accordance with what is prodicted by the solute drag-like ef-fect (SDLE) theory on the transformation kinetics.
