Abstract Scope |
Small-angle scattering is a useful approach for examining quantitative analysis of precipitation nanostructures, and also of compositional fluctuations in alloys. We would like to present our recent developments on resonant small-angle scattering measurements made at the K absorption edge of light metals, in particular, at Mg. Since the photon energy of such absorption edge are in the so-called tender X-ray region, i.e., around 1 keV, there are several experimental difficulties to overcome. By using the resonant scattering, control of contrast for Al3Mg nano precipitates in Al-Mg alloys and MgO nanoparticles supported on polymer membranes were confirmed.
Present approach is expected to be useful in examining not only the precipitation nanostructures or Mg nanostructures such as nanoparticles and pillars, but also the average structure in multilayered microstructures having large distribution. |
