抄録
Phase-field simulations of Widmanstätten ferrite formation during isothermal austenite-to-ferrite transformation in Fe-C alloys are carried out. The effects of the anisotropy of interfacial properties on the formation process of Widmanstätten ferrite are studied by the regularized gradient coefficient method in order to introduce strong anisotropy of the interface. The results suggest that the lengthening rate of the ferrite plate decreases with increasing interfacial energy because the growth rate to the broad side increases. With the constant interfacial energy at the broad side of the plate, the increase of the strength of anisotropy causes faster tip velocity and the formation of fine tips. Futhermore, simulation results clarified that the realistic morphology of Widmanstätten ferrite plate can be represented by using the regularized gradient coefficient method and that strong anisotropy of the interface is required for the formation of Widmanstätten ferrite plates from allotriomorph ferrite.
