界面性质对实际合金材料的凝固组织有重要影响。因此,有必要了解目标合金的界面性能,包括成分依赖性。本文采用分子动力学模拟结合毛细管涨落方法研究了Fe-Ni合金固液界面能的组分依赖性。富Ni组份呈FCC-固相时的固液界面能大于富Fe组份呈BCC-固相时的固液界面能。此外,固-液界面能在FCC-固相组成下比在BCC-固相组成下具有更高的各向异性。
Interfacial properties strongly affect solidification microstructure of practical alloy materials. Therefore, it is essential to understand interfacial properties including composition dependence for target alloys. In this study, composition dependence of solid-liquid interfacial energy of Fe-Ni alloy is investigated by molecular dynamics simulations in conjunction with a capillary fluctuation method. The solid-liquid interfacial energy of Ni-rich composition taking FCC-solid phase is larger than that of Fe-rich composition taking BCC-solid phase. Moreover, solid-liquid interfacial energy has a high anisotropy at the composition with FCC-solid phase compared to the one with BCC-solid phase.
