Strengthening of materials by multilayered structure has been used from a viewpoint of designing composite materials. In the present work, we extended a method to examine macroscopic layered structure containing modulated nanostructures from 1 dimensional scanning synchrotron radiation Small Angle X-ray Scattering (SAXS) to tomographic measurements. The specimen used in the present work were model three-layered Al alloy sheets prepared by hot rolling and cut into a rectangular rod.
2-dimensional mapping of voxel SAXS intensities were calculated from SAXS measurements, performed by scanning microbeam X-rays (15keV, φ5~20μm) with translating and rotating the specimen. Information about the size and amount of nanoscopic precipitate distributions of 1 and 2 dimensions normal to the specimen’s multilayer were acquired with a resolution of 20μm, regardless of isotropy. Measurements have been performed at the beam-line 40XU of SPring-8, Japan.
