The relative integral enthalpy, entropy, and Gibbs energy of liquid binary alloys of 3dtransition and noble metals are calculated. Only selectrons are considered as conductivity electrons. The role of partially populated dbands is reduced to resonance scattering of the selectrons by dstates. The interaction of selectrons with the ion subsystem, which does not possess the partially populated dstates, is described using the nonlocal model pseudopotential of electron–ion interaction. The interaction of the s and delectrons is described by the hybridization potential of s and dstates. As shown, the obtained analytical expression for relative integral Gibbs energy is a function of difference between the uniform parts of electron densities of the alloy components, and this difference is a factor, which determines mutual solubility of alloy components.
