Abstract

An overview of the phase-field method for modeling alloy solidification is presented together with several example results. Using a phase-field variable and a corresponding governing equation to describe the state (solid or liquid) in a material as a function of position and time, the diffusion equations for heat and solute can be solved without tracking the liquid-solid interface. The interfacial regions between liquid and solid involve smooth, but highly localized variations of the phase-field variable. The method has been applied to a wide variety of problems including dendritic growth in pure materials, dendritic, eutectic and peritectic growth in alloys and solute trapping during rapid solidification.
