X-ray anomalous scattering phenomena applied to the interpretation of diffuse scattering from ternary metallic solid solutions

Recent attempt at applying X-ray anomalous scattering phenomena to the study of local atomic arrangements in ternary metallic solid solutions are reviewed. Diffuse scattering intensity is measured over a volume of reciprocal space at the wavelengths near the absorption edges of constituent atoms using synchrotron radiation and is decomposed into partial intensities arising from different kinds of interatomic spatial correlations. In the region around the Bragg reflections, it is possible to separate the local order diffuse scattering from the pronounced temperature diffuse scattering. (author)
