## Description

- description: 'The stability of solid-solution phases in FCC and BCC lattices was
    examined in multi-component alloys based on the CALPHAD technique using the compound
    energy formalism and regular solution model. From the thermodynamic calculations,
    it was found in ternary systems that the single solid-solution phase became stable
    around the equiatomic composition where the configurational entropy was the largest
    value. The transition temperatures decreased with the increasing number of elements
    in the system. The A1/L10 transition temperature was affected by the stoichiometric
    compositions of the ordered phases existing at the equiatomic composition, whereas
    it was not significant for the A2/B2 transition in the two-sublattice model. The
    single solid-solution phase region at equiatomic compositions was affected by
    variations in the interaction parameters. In multi-component systems, the variations
    were averaged with increasing the number of elements in the system. This suggests
    that high-entropy alloys can afford a variety of elements. '
