摘要
A new thermodynamic assessment of the Co-Nb system is presented. All experimental phase diagram data available from the literature have been critically reviewed and assessed using thermodynamic models for the Gibbs energies of the individual phases (Thermo-Calc). Compared to previous assessments more elaborate models for the description of the C 14 and C36 Laves phases and for the It phase were employed. Thereby a calculated phase diagram is obtained which satisfactorily agrees with the experimental data.
