Abstract

The temperature dependences of the dynamic viscosity of the InBi_{100 – x}Pb_x (where x = 19, 40, 60, 80, and 100 at %) melts are studied in the range from the liquidus temperature to 1200 K by the oscillating crucible method. The temperature dependences of the viscosities of melts of these compositions are well described by the Arrhenius equation. The viscosity of the InBi–Pb melts at a constant temperature has small negative deviations from the ideal mixture viscosity. The activation energy of a viscous flow has negative deviations from additive values with a minimum near 20 at % Pb. The concentration dependences of the viscosities of the melts are calculated using the well-known equations based on the thermodynamic properties. The obtained results are compared with the experimental data.

InBi–Pb熔体的粘度

摘要

InBi _{100 – x} Pb _x（其中x通过振荡坩埚法研究了在液相线温度至1200 K范围内的熔体（= 19％，40％，60％，80％和100 at％）的熔体。这些组合物的熔体粘度的温度依赖性由Arrhenius方程很好地描述。InBi–Pb熔体在恒定温度下的粘度与理想混合物的粘度之间存在较小的负偏差。粘性流的活化能与添加剂值之间存在负偏差，最小值最小为20 at％Pb。基于热力学性质，使用众所周知的方程式来计算熔体的粘度的浓度依赖性。将获得的结果与实验数据进行比较。
