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 high-entropy alloy does not need to be equimolar, or close to it.

Example usage of the term "high-entropy alloy" or an example of high-entropy alloy?

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.
