用相场法研究了Fe-C-M（M为替位元素）合金中界面共格在奥氏体向铁素体转变动力学中的作用。结果表明，非相干界面具有比半相干界面高得多的本征迁移率，但非相干界面处的溶质拖曳效应也更为显著。在考虑溶质的相干拖曳效应时，半相干界面对相变动力学的贡献不可忽略。
The role of interfacial coherency in the kinetics of austenite to ferrite transformation in Fe-C-M (M is a substitutional element) alloys is studied with phase field method. It is found that while incoherent interfaces possess a much higher intrinsic mobility than semicoherent interfaces do, the solute drag effects at incoherent interfaces is also more significant. The contribution of semicoherent interfaces to transformation kinetics may not be ignored if the coherency-dependent solute drag effects are considered.
