用CALPHAD方法对Ag-Yb二元系进行了热力学计算。将液相、体心立方相和面心立方相作为置换相处理，用Redlich-Kister多项式函数表示其超额吉布斯自由能。将二元金属间化合物作为化学计量相处理。获得了一组描述该体系各相的自洽热力学参数，可以很好地再现相应的实验数据。
The Ag–Yb binary system has been thermodynamically assessed with CALPHAD approach. The solution phases including liquid, bcc and fcc were treated as substitutional solution phases, of which the excess Gibbs energies were formulated with Redlich–Kister polynomial functions. The binary intermetallic compounds were treated as stoichiometric phases. A set of self-consistent thermodynamic parameters for describing various phases in this system has been obtained, which can well reproduce the corresponding experimental data.
