Abstract Scope |
Demands for synchrotron-based 3D characterization for materials in manufacturing industries are shifting from modeled specimens or small test pieces to mass-produced components without any cutting. The upgrade of SPring-8 named SPring-8-II will meet the demands of high-energy X-rays, because brilliant high-energy undulator radiation with an energy band width of 1% will be obtained without any monochromators. We have tested the concept of a so-called high-energy pink beam using a double multilayer monochromator designed for 100 keV. In this presentation, we show some results of 3D imaging and diffraction experiments using the 100-keV pink beam based on industrial demands. Computed laminography, for instance, enabled 3D imaging of voids in die-attach solder in a power semiconductor module for automotive applications. Laminographic 3DXRD enabled 3D orientation mapping for a 9-mm-thick steel plate as a milestone toward the characterization of plastic deformation, creep, and fatigue of polycrystalline materials embedded in manufactured components and products. |
