Small-angle scattering measurements utilizing anomalous dispersion effect just below the Zr and Ni K edge have been made for welded Zr-based amorphous materials. The measurements were carried out at a bending magnet beam-line 40B of SPring8. A small and parallel X-ray beam generated at the third generation synchrotron is suitable for nanostructure mapping of heterogeneous materials, whose structure varies with less than a millimeter scale. The remelted and heat-affected zones were examined for electron-beam welded Zr-Ni-Cu-Al alloys. Merits and the characteristics, as well as its present limitations of scanning small-angle scattering with a use of anomalous dispersion effect is discussed as a tool to examine microstructure in the spatially inhomogeneous materials in macroscopic scale as well as microscopic scale.
