   The high-entropy alloy definition should be measured by the configurational entropy (per atom) for a given composition. High-entropy alloys do not necessarily have exceptional mechanical properties. Often, they don't.

    A subset of MPEAs where elements are in near-equiatomic ratios, and high configurational entropy stabilizes single-phase solid solutions. One can generate such kind of disordered materials using Boltzmann distributions.
