Abstract

A systematic and generalized procedure for mathematical formulation of latent heat functions, as applicable for enthalpy-based solidification modeling of multicomponent alloy systems, is developed. The method uses a metallurgically appropriate thermo-solutal coupling strategy, in conjunction with updating of respective phase fractions, in order to obtain solutions of field variables that are consistent with the pertinent phase-change morphology. The present approach can model the solidification of multicomponent alloys for a wide range of local scale diffusion behavior of the constituent species.
