在1100℃、1200℃和1300℃等温截面实验测量的基础上，采用相图计算方法对Nb-Si-Ta三元系进行了热力学计算，并根据文献报道的Nb-Si、Nb-Ta和Si-Ta三种二元体系的热力学参数进行了优化。根据目前已有的Nb-Si-Ta系热力学描述，计算了相线推算。计算结果与实验结果的比较表明，该模型能较好地描述Nb-Si-Ta三元相图的实验信息。
The Nb-Si-Ta ternary system is thermodynamically assessed using the CALculation of PHAse Diagram approach based on the experimental measurements of the isothermal sections at 1100, 1200, and 1300 °C. The parameters for the thermodynamic assessment of all the phases in the system are optimized, following the reported literatures of the three relevant binaries Nb-Si, Nb-Ta and Si-Ta systems. The liquidus projection was calculated accordingly from the currently obtained thermodynamic description of the Nb-Si-Ta system. Comparison between the calculated results and the experimental investigations shows that the present modeling can finely describe the experimental information of the Nb-Si-Ta ternary phase diagram.
