Thermodynamic computation of the Mo-V binary phase diagram

The available phase diagram and thermodynamic data for the Mo-V system has been reviewed and an attempt made to optimize the system using the Lukas program. This was unsuccessful, probably due to insufficient and inconsistent experimental data. The best fit to the experimental phase diagram data was obtained using Brewer and Lamoreaux’s Gibbs energy expressions and the pure element data recommended by SGTE. Equations are given for the temperature/composition dependence of the liquidus and solidus curves.
