Based on the experimental data of phase diagram and thermodynamic properties, the U-Sn system was assessed using the CALculation of PHAse Diagrams (CALPHAD) method. The Redlich-Kister model was used for the description of the liquid phase. A set of self-consistent thermodynamic parameters describing all condensed phases was obtained. The calculated results in this work are in good agreement with available phase equilibria data and thermodynamic data. The tentative U-Zr-Sn ternary system was constructed by extrapolation method and the available ternary experimental data from literature can be reasonably reproduced using the current thermodynamic description.

U-Sn系统的热力学评估以及对U-Zr-Sn系统的扩展

基于相图和热力学性质的实验数据，使用PHAse图的计算（CALPHAD）方法对U-Sn系统进行了评估。Redlich-Kister模型用于描述液相。获得了一组描述所有冷凝相的自洽热力学参数。这项工作的计算结果与可用的相平衡数据和热力学数据非常吻合。通过外推法构建了暂定的U-Zr-Sn三元体系，使用当前的热力学描述可以合理地复制文献中可用的三元实验数据。
