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