The paper presents the results of molecular dynamics study of the viscosity of nickel-containing binary metal melts for a wide range of temperatures, including the region of the equilibrium liquid phase and supercooled melt. It is shown that the temperature dependencies of the viscosity of binary metal melts are described by the Kelton's quasi-universal model. Based on the analysis of the viscosity coefficient of the binary melt composition within the framework of the Rosenfeld's scale transfor\-mations, it has been established that to correctly describe the viscosity of binary/multi\-component metal melts within the framework of entropy models, it is necessary to use a more complex representation of the excess entropy $S_{ex}$ than in the approximation of pair correlation entropy $S_2$.

含镍二元金属熔体的粘性特性

本文介绍了含镍二元金属熔体粘度在很宽的温度范围内的分子动力学研究结果，包括平衡液相和过冷熔体区域。结果表明，二元金属熔体粘度的温度依赖性由 Kelton 准通用模型描述。基于在 Rosenfeld 尺度变换框架下对二元熔体成分粘度系数的分析，建立了在熵模型框架内正确描述二元/多组分金属熔体粘度的方法。 ，有必要使用比对相关熵 $S_2$ 的近似更复杂的超熵 $S_{ex}$ 表示。
