AbstractPrepeaks in the partial structure factors of liquid alloys are interpreted as a modulation in the diffuse Laue-scattering, caused by chemical short range order. It is shown and experimentally confirmed that the partial structure factors can become lower than -1. It is unlikely that a modulation appears in only one of the three partials; rather a chemical short range order should be indicated in all three partial structure factors.

The Difference

Electron distribution in liquid metals and charge transfer in liquid alloys are qualitatively and quantitatively discussed in terms of the structure factors and the thermodynamic quantities obtained experimentally. The electron distribution around an ion in liquid metals has been derived from the difference in structure factors determined by X-ray and neutron-diffraction methods with the help of a theoretical calculation of the electron–electron correlation function. Charge transfer in liquid alloys is also estimated by using the partial structure factors in the long-wavelength limit and the Thomas–Fermi screening theory. The charge-transfer effect in liquid alloys is also verified by the measurements of partial structure factors and magnetic susceptibilities.

Thermal Diffusion Ratio

The model of conformal solutions, introduced to study the thermodynamics of liquid mixtures by Longuet-Higgins, is used to calculate the partial structure factors S ij ( q ) of a binary liquid. Explicit expressions are given, in terms of the pair interaction and the radial distribution function for the reference liquid, for the number-concentration structure factors of the mixture. Results are also obtained for transport properties, in particular for interdiffusion and thermal diffusion ratio. Finally some relevant experiments are proposed.

AbstractThe structure of monoatomic liquids in the static approximation is described by a soft sphere model and the corresponding equation of state is derived. This geometrical model is then extended to binary liquid or amorphous substitution alloys where both components have the same size. The structure of these alloys is shown to be determined by the first neighbour order parameter which is positive, negative or zero for segregated, ordered or disordered alloys respectively. The variations of the partial structure factors with concentration are presented for these three cases. Size effects are then studied by varying the ratio of atomic diameters. Many experimental results are shown to fit this simple framework.
