Notes:
The strain in the bulk of material was evaluated using high energy white X-rays from asynchrotron radiation source of SPring-8 in Japan. An austenitic stainless steel (JIS-SUS304L) wasused for a specimen. The specimen of 5 mm thickness was subjected to the bending. The internal strainof it could be measured using white X-rays which range of energy from 60 keV to 125 keV. Themeasurement of the internal strain with a high accuracy was accomplished using the strain data fromseveral lattice planes of γ-Fe simultaneously. Furthermore, the measurement error of strain could bedecreased by using the diffracted beam with high energy, high peak count and the similar profile withthe Gaussian distribution. The results showed that the high energy white X-rays is effective for theinternal strain measurement in the depth of the order of millimeter
