| Outline of Final Research Achievements |
Imaging experiments have been performed at first for aluminum using the X-ray energy of 20 keV and subsequently for steels et al. using 30 keV or more, which was realized by combining a large-scale X-ray microscope and a phase contrast technique. The projection CT, by which the whole sample is visualized and the X-ray microscope were combined with an adjoining XRD setup with a collimated X-ray beam, thereby the evaluation of the-whole-sample and full-time observation of the weakest point is realized in spite of the high-resolution observation. In addition, the coarsening techniques, which analyzes a huge number of microstructural features in a 3D image, was studied. Dislocations and vacancies, and polycrystalline structures were measured in 3D in high density by employing our original 3D plastic strain mapping and diffraction-amalgamated grain boundary tracking technique, respectively. This enables us to conduct the real multi-scale imaging ranging between nanoscale and macroscale.
