The viscosity and liquid structure of (, ,,, at.%) melts were investigated. Temperature dependence of viscosity and correlation length all shows an exponential decay function (Arrhenius-type equation), which is similar to our former studied Cu-Ag alloys. The correlation between viscosity and liquid structure had been studied. A simple relation between viscosity and correlation length was found. The ratio of and shows a linear relationship with temperature, which is different from our former studied results in Cu-Ag alloys. Among the four Cu-Sn alloys, and alloys have higher activation energy for viscous flow , activation energy for structural evolution , and the slope of the linear relationship of / with temperature due to the clusters formation.

Cu-Sn 合金中粘度和液体结构之间的直接关系

研究了 (, ,,,, at.%) 熔体的粘度和液体结构。粘度和相关长度的温度依赖性都显示出指数衰减函数(Arrhenius 型方程),这类似于我们之前研究的 Cu-Ag 合金。已经研究了粘度和液体结构之间的相关性。发现了粘度和相关长度之间的简单关系。和的比值与温度呈线性关系,这与我们之前在 Cu-Ag 合金中研究的结果不同。在四种 Cu-Sn 合金中,由于团簇的形成,合金具有较高的粘性流动活化能、结构演化活化能以及 / 与温度的线性关系的斜率。
