The partial and integral enthalpies of mixing of liquid ternary Ni-Sn-Zn alloys were determined. The system was investigated along two sections xNi/xSn ≈ 1:9, xNi/xSn ≈ 1:6 at 1073 K and along two sections xSn/xZn ≈ 9:1, xSn/xZn ≈ 4:1 at 873 K. The integral enthalpy of mixing at each temperature is described using the Redlich-Kister-Muggianu model for substitutional ternary solutions. In addition, the experimental results were compared with data calculated according to the Toop extrapolation model. The minimum integral enthalpy of approx. −20000 J mol-1 corresponds to the minimum in the constituent binary Ni-Sn system, the maximum of approx. 3000 J mol-1 is equal to the maximum in the binary Sn-Zn system.

液态镍锡锌合金的混合焓

确定了液态三元 Ni-Sn-Zn 合金的部分混合焓和整体混合焓。在 1073 K 下沿 xNi/xSn ≈ 1:9、xNi/xSn ≈ 1:6 和 xSn/xZn ≈ 9:1、xSn/xZn ≈ 4:1 在 873 K 下沿两个截面研究系统。积分每个温度下的混合焓使用 Redlich-Kister-Muggianu 模型描述替代三元溶液。此外，将实验结果与根据 Toop 外推模型计算的数据进行了比较。大约的最小积分焓。-20000 J mol-1 对应于组成二元 Ni-Sn 系统中的最小值，最大值约为。3000 J mol-1 等于二元 Sn-Zn 系统中的最大值。
