The phase-field model is a powerful computational tool for solving free-boundary problem (FBP) of solid–liquid interface. Quantitative phase-field models, which can be mapped onto FBP in thin-interface asymptotics, have enables quantitative simulation of solidification microstructures. Recently a way of formulation of the quantitative phase-field model based on a variational principle from free energy functional was developed for isothermal solidification in a dilute binary alloy. In the present study, this variational approach is extended to deal with non-isothermal solidification in multi-component alloys. This model is suitable for simulations of practical alloy systems because one can utilize any type of free energy models such as the solution models in CALPHAD method. In this talk, this model is explained with some examples of its applications to alloy solidification processes.
