CALCULATION OF BAINIT TRANSFORMATION KINETICS IN Fe-C-Si-Mn ALLOYS
Fe—C—Si—Mn系合金贝氏体相变动力学计算

Both regular solution and supper-component models were used to calculate the driving force for isothermal transformation of Fe-C-Si-Mn alloys. The relative nucleation 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 the driving 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.
