| Outline of Final Research Achievements |
Anomalous small-angle X-ray scattering system for contrast change using resonant effect at K absorption edges of Aluminum and Magnesium has been designed and constructed for realizing contrast enhancement to measure small-angle scattering from low-Z aluminum alloys, i.e., Al-Mg and Al-Mg-Si. To visualize Fourier transform of the scattering patterns by strengthening nanoclusters and nanoprecipitates, establishing quantitative measurements at the tender X-ray region is a new and technically difficult requirements.
We have shown that resonant small-angle scattering at the K absorption edge of Aluminum by Alumina nanoparticles and precipitates in Al alloy systems agreed with theoretical prediction given by Cromer-Liberman calculations.
