【摘要】 本研究通过关键实验与热力学计算对Nb—Ni二元系进行了重新评估。首先对文献中所有的相图实验数据与热力学实验数据进行了评估。然后考虑本研究所获得的实验结果及文献中可信的实验数据,包括最近的液相混合焓的实验数据与μ相晶体学的实验数据,采用分步优化的方法,获得了一套自恰的Nb—Ni二元系热力学参数。根据这套参数计算的相图及热力学性质与实验数据非常吻合。更多还原

【Abstract】 The Nb-Ni binary system is reassessed via key experiments and thermodynamic modeling. All the experimental phase diagram and thermodynamic data available from the literature are critically reviewed. The step-by-step method was used in the optimization and a consistent thermodynamic data set for the Nb-Ni system is obtained by considering the present experimental data in this work and reliable data from literature including the recent experimental data on the enthalpies of mixing of the liquid and the recent crystallographic data on the u phase. The calculated phase diagram and thermodynamic properties agree with the experimental data very well.更多还原
