基于在1000、1150、1200、1340和1500摄氏度下的实验等温截面，以及来自文献和当前测量的液相线投影，对Nb - Si - Ti系进行了热力学评估。按照已报道的Nb - Si、Ti - Si和Ti - Nb二元系的描述，对三元系的热力学描述参数进行了优化，其中根据相关的二元实验数据对Nb - Si系的一些参数进行了修改。计算结果与实验研究的比较表明，当前的模型能够很好地描述Nb - Si - Ti三元相图的实验信息。(C) 2008爱思唯尔有限公司。保留所有权利。
The Nb-Si-Ti system is assessed thermodynamically based on the experimental isothermal sections at 1000, 1150, 1200,1340 and 1500 degrees C, and the liquidus projections from both literatures and the present measurements. The parameters for the thermodynamic description of the ternary system are optimized following the reported descriptions of the Nb-Si, Ti-Si and Ti-Nb binary systems, among which some of the parameters of the Nb-Si system are modified according to its related binary experimental data. Comparison between the calculated results and the experimental investigations shows that the present modeling can finely describe the experimental information of the Nb-Si-Ti ternary phase diagram.
