摘要
The viscosity and liquid structure of Cu100-xSnx(x = 10, 20, 30, 40, at.%) melts were investigated. Temperature dependence of viscosity eta and correlation length D all shows an exponential decay 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 D was found. The ratio of D and eta shows a linear relationship with temperature, which is different fromour former studied results in Cu-Ag alloys. Among the four Cu-Sn alloys, Cu80Sn20 and Cu-70 Sn-30 alloys have higher activation energy for viscous flow (E-a,E-V), activation energy for structural evolution (E-a,E-D), and the slope (gamma) of the linear relationship of D/eta with temperature due to the Cu3Sn clusters formation.
