摘要
Based on the nonlinear interaction of the different species and the calculation of phase diagram,a self-consistent model is developed to describe the interface morphology evolution during unidirectional solidification of multicomponent alloys.This model takes full account of the mutually coupled effect of temperature field,solute field,interface energy and interface attachment kinetics.In comparison with linearization analysis of multicomponent,it not only extends the convergent range of the analysis,but also greatly improves the applicability.
