概要

In this study, stress measurements were performed using a double exposure method with hard synchrotron monochromatic X-rays, and its validity was proved. The diffractions of the shrink-?tted ring of austenitic stainless steel SUS304 were measured by the CdTe pixel detector. The used X-rays were 70, 80 and 90 keV. The measured stress distributions with the 311 diffraction of γ-Fe corresponded to the predicted result. In addition, The stress distribution of the shrink-?tted ring was measured by the CCD camera with monochromatic synchrotron X-ray of about 70 keV. Although enough precision was not obtained from the measured result, the measured stress distribution expressed the feature of the shrink-?tted ring. This is caused by the low diffraction angle and the short distance between the detectors.
