用分子动力学模拟方法研究了过冷Ni6Cu4熔体成核的动力学细节。结果表明，原子核是大量fcc结构和少量hcp结构的随机混合物。晶核的生长速率随过冷度(ΔT)呈线性增加。结果表明，Ni6Cu4过冷液中的显微组织演变明显。
The kinetic details of the nucleation in a supercooled Ni6Cu4 melt are investigated using molecular dynamics simulation method. It is indicated that the nucleus is a random mixture of a large number of fcc structures and a small number of hcp structures. The growth rate of the nucleus increases linearly with undercooling (ΔT). The results show the microstructure evolution in the supercooled liquid of Ni6Cu4 clearly.
