Viscosity, Resistivity and Structural Changes of Bi60Ga40 Alloy Melt with Liquid-liquid Phase Separation

摘要：

The temperature dependence of viscosity of liquid Bi60Ga40 alloy has been measured using torsional oscillation viscosity measurement. The results show that the change of viscosity with temperature is distinctly discontinuous, which can be divided into three parts: the changes in high temperature region, mid-temperature region, as well as low temperature region. In these different regions, the structures of melt are distinct. There is only low temperature anomalous point on the resistivity-temperature curve in liquid-liquid phase separation zone. The appearance of exothermic peaks on DSC curve during cooling process further proved the structure changes of melt in 893K-923K. The liquid-liquid phase separation is naturally accompanied with structure change of melt in 535K-563K, which is also reflected by the discontinuous change of viscosity and DSC analysis.
