The thermodynamic approach for evaluation of stability of multicomponent substitutional solid solutions by means of the determination of their Gibbs free energy is developed. The refractory W–Nb–Mo–Ta–V and W–Nb–Mo–Ta systems are investigated using this approach. As shown, the high-entropy W38Nb17Mo21Ta19V5 and W37Nb21Mo19Ta23 alloys are the most heat-resistant. The correlations between the distribution of elements in real alloys and predicted compositions are obtained.
