Abstract
The entropies of mixing of liquid metals are well explained on the basis of a hard-sphere model in which (i) the total ionic volumes are supposed not to change on alloying and (ii) the observed excess volumes are incorporated into the calculation. The above propositions are illustrated by the consideration of 31 binary alloys in the middle of their composition ranges and of seven such systems across their whole ranges. The formalism also yields a qualitatively correct description of specific heats of alloys in so far as the limited experimental information permits us to judge.Keywords
