Abstract: We report on the characterisation of embedded Al₂Cu nanoparticles in Al matrix by X-ray diffraction imaging and small-angle X-ray scattering. We employed direct retrieval of the average morphological characteristics of the nanoparticles from their diffraction pattern. Data suggest the possibility of acquiring truly 3D information with X-ray diffraction imaging. Validation of the results obtained with small-angle X-ray scattering is reported.

Keywords: X-ray diffraction imaging; small-angle X-ray scattering; embedded nanoparticles; nanoprecipitates; nanotechnology; aluminium; copper.
