通过测量不同外磁场条件下熔体的动态粘度，研究了不同不混溶合金CdGa和比加的双结点温度的变化规律。凝固过程中的温度变化受能垒控制。提出了一个能垒方程来定量计算不相容合金液相分离过程的活化能。建立了能垒与磁场强度的关系。磁场不仅使不互溶合金的熔体粘度增加，而且使熔体强度增加。随着磁场强度的增加，不互溶合金的双结点温度明显向高温移动。揭示了不互溶合金粘度随温度降低而降低的反常现象。
The variation of the binodal temperatures for the different immiscible alloys, CdGa and BiGa, was determined through the dynamic viscosity measurements of melts under various external magnetic field conditions. The binodal temperature change was controlled by an energy barrier during solidification. An energy barrier equation is proposed to quantitatively calculate the activation energy during liquid phase separation process for the immiscible alloys. The relationship between the energy barrier and the magnetic field intensity has been established. The magnetic field not only causes an increase of melt viscosity for the immiscible alloys but also makes the melts becoming much stronger. The binodal temperature of the immiscible alloy obviously shifts to higher temperature as the magnetic field intensity increases. An anomaly that the viscosity of immiscible alloys decreases with decreasing temperature is uncovered.
