The assessment of the Co-Zr system was carried out in the frameworks of the CALPHAD-method. Composition dependence of the excess Gibbs energy of liquid alloys and solid solutions in the system was described using Redlich–Kister polynomials. Compound Energy Formalism was used to describe the thermodynamic properties of intermetallic compounds. The current assessment takes into account a complete set of experimental data on the thermodynamic properties of the phases and phase equilibria. The phase diagram, coordinates of invariant equilibria, and thermodynamic properties of liquid and solid phases are calculated.

Co-Zr 系统的热力学评估

Co-Zr 系统的评估是在 CALPHAD 方法的框架中进行的。使用 Redlich-Kister 多项式描述了系统中液态合金和固溶体的过量吉布斯能量的组成依赖性。复合能量形式主义用于描述金属间化合物的热力学性质。当前的评估考虑了关于相的热力学性质和相平衡的一组完整的实验数据。计算了液相和固相的相图、不变平衡坐标和热力学性质。
