中文摘要：
把常规答案模型，基于候补选手液相分离第三(Ni x Cu 100−x )50 Pb 50 monotectic 合金被阶段场地方法模仿。如果表面分离潜力没被合并，合金的动态形态学融化表演，这被发现转变从驱散微观结构进双性人有流动性的增加的连续微观结构参数。当表面分离潜力被联合时， Pb 富有的阶段优先地移居到液体合金的表面，并且 Ni 富有的阶段取决于 Pb 富有的阶段起核心作用。与阶段分离时间的延期，表面层通过凝结和生长被形成，并且它的厚度逐渐地增加。Ni 富有的阶段移居到中央部分，并且最后，二层的核心壳微观结构被生产。在表面层的集中在体积阶段内比那更显著地波动，它随后由一个波浪从表面转到内部。液体液体接口附近的液体域以后在阶段分离，和还原剂的开始是强壮的。表面分离对表面层，集中侧面变化，液体地分发和阶段分离形态学的形成必要。
英文摘要：
Based on the subregular solution model, the liquid phase separation of ternary （NixCU100-x）50Pb50 monotectic alloys is simulated by the phase field method. It is found that if the surface segregation potential is not incorporated, the dynamic morphologies of alloy melt show a transition from disperse microstructure into bicontinuous microstructure with the increase of fluidity parameter. When the surface segregation potential is coupled, Pb-rich phase migrates preferentially to the surface of the liquid alloy, and the Ni-rich phase depends on the Pb-rich phase to nucleate. With the extension of the phase separation time, the surface layer is formed through coagulation and growth, and its thickness gradually increases. The Ni-rich phase migrates to the central part, and finally a two-layer core-shell micro- structure is produced. The concentration in the surface layer fluctuates more conspicuously than that inside the bulk phase, which subsequently transfers from the surface to the interior by a wave. The fluid field near the liquid-liquid interface is strong at the beginning of phase separation, and reduces later on. The surface segregation is essential to the formation of the surface layer, concentration profile variation, fluid field distribution and phase separation morphology.
