Abstract
The Wagner interaction parameter ɛ AuAu and first-order enthalpy parameter η AuAu in Cu-Au melts at 1550 K were calculated in terms of the lattice solution model and statistical theory of low-concentration melts. The h i potential of the approach of two gold atoms in the face-centered cubic lattice of copper was used. The theoretical parameter ɛ AuAu = 3.2 was satisfactorily close to the experimental value ɛ AuAu = 3.7, whereas the theoretical enthalpy parameter agreed with its experimental value only in sign and the order of magnitude.
