A phase field model for solidification of ternary alloys is proposed. In this paper, the relations between material properties and phase-field parameters are presented. In the development of this work, the ternary-alloy solidification model for the analysis of diffusivity is employed. For two-dimensional computations, the dendritic growth is simulated for Fe-C-P ternary alloys. The change in phosphorus concentration affects the interface velocity. This change in the interface velocity is due to the small diffusivity of phosphorus during the solidification process.
