Thermodynamic Assessment of the Nb–W–C System
-
Weiming Huang
Abstract
The phase equilibrium and thermodynamic information of the Nb–W–C system was reviewed and assessed by using thermodynamic models for the Gibbs energy of individual phases. The assessment was based on the recent evaluations of the W–C, Nb–W and Nb–C, which was revised in the present work taking ternary information into account. The model parameters were evaluated by fitting the selected experimental data by means of a computer program. A consistent set of parameters was obtained, which satisfactorily describes most of the experimental information.
