Abstract Scope |
Multilayered structure has been used from a viewpoint of designing composite materials, to manufacture strong materials in the industry. In the present work, we used the method developed in the last report to examine nanostructure distribution in a layered structure containing macroscopic compositional modulation. A tomographic measurement using synchrotron radiation Small Angle X-ray Scattering (SAXS) signal was conducted for a 3-layered rectangular rod specimen of Al-Zn-Mg alloys, prepared by hot rolling and cut from a 3-layered sheet.
A 2D absorption coefficient tomography in the absolute value was reconstructed for a cross section of specimen pillar. The 2D integrated intensity tomography was also reconstructed in the same cross section, caused by the nanoscopic precipitates from SAXS measurement, in the direction normal to the cross section. Measurements have been performed at the beam-line 40XU of SPring-8, Japan. |
