| Outline of Final Research Achievements |
In order to verify experimentally the relation between the progress of ductile damage and crystal orientation, the X-ray diffraction measurements of a single crystal is valid. In this study, verification of the ductile damage progress behavior of an aluminum single crystal under tensile loading was performed by using white X-ray at synchrotron radiation facilities SPring-8. As a result, dislocation cells were generated and rotated near the notch with ductile damage progress. The angle variations in the vertical plane are very large compared with them in a horizontal plane. And, dislocation density increased as ductile damage progressed, but it was relatively low near the notch. The influence of release of the strain energy by ductile damage progress was expected.
