The results indicate that,with increase in undercooling,a small nuclei will grow developed dendritic,the tip velocity at steady state is become faster;With increase in the coupling parameter,tip velocity at steady state increased monotonically and it's interfacial stabil.
结果表明,随着过冷度值的增加,晶核由一圆核逐渐发展为发达的枝晶,相应的枝晶稳态尖端速度明显加快;随着耦合系数的增大,晶核由一圆核发展为细长的枝晶,枝晶的稳态尖端速度呈单调递增趋势,界面的稳定性逐渐变差。
