摘要 | A phase-field method for two-dimensional numerical simulation of binary alloy during directional solidification is studied, the evolution of the interface morphology is showed and the effects of phase-field parameters on interface morphology are formulated for Ni-Cu binary alloy. The results indicate that, with the decrement of interface width, the transition of cells to dendrites occur, the tip velocity was increasing and the stability of the tip was descending. The smaller the anisotropy is, the smaller the tip velocity is, and the easier the side-branches grow and form cellular dendrites. The amplitude of fluctuation α has an important effect on the interface morphology. When an appropriate value is assigned to a, the noise can enhance the emergence of side-branches, and form cellular dendrites, and influence the tip velocity at the same time. |
