A Direct Correlation between Viscosity and Liquid Structure in Cu-Sn Alloys

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.
