摘要:
A hyperbolic phase-field model (PFM) was proposed from the thermodynamic extremal principle for rapid solidification of a binary alloy. In the modeling, not only the interface but also the bulk phases are under non-equilibrium conditions. Dissipation inside the interface, its relations to the sharp interface models, and the previous PFMs are discussed. The solute diffusion in liquid splits into the long-range solute diffusion and the short-range solute redistribution between solid and liquid if ...More
