Tomographic images with absolute units have been reconstructed successfully from Small Angle X-ray Scattering (SAXS) intensities of an interdiffusion layer of a precipitation strengthened model alloy cut from a multilayered Al/Al–Zn/Al sample after heat treatment. Cross sectional images of specimen with Zn concentration distribution was obtained from the absolute X-ray mass attenuation coefficient; the volume fraction of precipitates from the absolute SAXS integrated intensity in each voxel. Mechanical property of the same cross-section was estimated from the nanostructure and composition obtained for each voxel determined by the reconstructed images.
