The partial and integral enthalpies of mixing of liquid ternary Ni-Sn-Zn alloys were determined. The system was investigated along two sections / ≈ 1:9, / ≈ 1:6 at 1073 K and along two sections / ≈ 9:1, / ≈ 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 corresponds to the minimum in the constituent binary Ni-Sn system, the maximum of approx. 3000 J mol is equal to the maximum in the binary Sn-Zn system.
测定了液态三元Ni-Sn-Zn合金的混合偏焓和混合积分焓。在1073K下沿两条截面/≈1:9、/≈1:6对该体系进行了研究，在873K下沿两条截面/≈9:1、/≈4:1进行了研究。每个温度下的混合积分焓用替代三元溶液的Redlich-Kister-Muggianu模型进行描述。此外，还将实验结果与根据Toop外推模型计算的数据进行了比较。约-20000J/mol的最小混合积分焓对应于二元Ni-Sn体系中的最小值，约3000J/mol的最大值等于二元Sn-Zn体系中的最大值。
