High entropy metallic glasses, what does it mean?

We performed calorimetric measurements on 30 bulk metallic glasses, each differing in their mixing entropies Δ S mix . On this basis, the excess entropies Δ S and excess enthalpies Δ H of glasses with respect to their maternal crystalline states are calculated. It is found that the excess entropy Δ S on the average decreases with increasing mixing entropy Δ S mix . This means that the so-called “high-entropy metallic glasses” (i.e., the glasses having high Δ S mix ) actually constitute glasses with low excess entropy Δ S . We predict that such glasses should have reduced relaxation ability. We also found that the excess enthalpy Δ H of glass linearly increases with its excess entropy Δ S , in line with a general thermodynamic estimate.
