Phase-field model for solidification of ternary alloys coupled with thermodynamic database

Abstract A phase-field model coupled to real thermodynamic data in which the vanishing kinetic coefficient condition is proposed. The validity of the model is examined by comparing the calculated result of the equilibrium state with theoretical predictions for both one and two-dimensional simulations. Numerical simulations of micro-segregation and isothermal dendrite growth is presented to demonstrate the effectiveness of the model.
