摘 要：Nonequilibrium thermodynamics and transportation kinetics near the propagating solid-liquid interface dominates the rapid solidification process,which is far from a thermodynamically stable state.Rapid solidification process can be described more precisely using quantitative thermodynamic calculation of phase diagram with nonlinear liquidus and solidus and evaluating the nonequilibrium effect in diffusion kinetics.Based on these basic principles,we used a current nonequilibrium dendrite growth model to describe rapid solidification process of deeply undercooled alloys.Evolution of the key fundamental solidification parameters was also evaluated.
