Simulation of dendritic crystal growth of pure Ni using the phase-field model
The phase-field model is used in the numerical simulation of dendritic crystal growth in pure Ni in supercooled melt. Effect of anisotropy, undercoolings and thermal noise on the dendritic crystal growth is investigated in this paper. The simulated results indicate that with anisotropy increasing, growth rate of dendrite tip is accelerated and characteristic of dendritic structure is more obvious; As the degree of supercooling increases, stability of dendrite tip will be damaged, the dendrite tip branching-off will happen. Stirring power can promote side-branching, but does not affect growth state of dendritic crystal.
