The partial structure factors of liquid Cu-Sn

Abstract

A detailed analysis of the diffraction pattern of liquid Cu₆Sn₅ has been carried out using neutron techniques. The scattering powers of the alloys were changed by isotopic substitution and the three structure factors required to specify a binary liquid alloy were calculated. It is found that both copper-copper and tin-tin correlations are clearly defined, and that the long-range concentration fluctuations are important in the copper-tin correlation. Some general remarks about the problem of obtaining the three structure factors for binary alloys are also made.
