Summary

It is shown that long-wavelength concentration fluctuations in a binary liquid metal alloy are determined by a pair interchange free energyw, which is exactly given by the sum of an elastic strain term and of the concentration-concentration direct correlation function. The latter is evaluated in an alloy of homovalent components by electron screening theory in the pseudopotential approach of Shaw and Harrison and shown to be entirely determined by nonlocal terms reflecting charge transfer to the more electronegative alloy component. Numerical calculations for the liquid Na−K alloy show strong cancellation between the two contributions tow at all concentrations, in qualitative agreement with experiment.
