Residual stress measurement is important to understand SCC (Stress Corrosion Cracking) process. In this study, CT (Computed Tomography) imaging and inner strain mapping of steel material (alpha-Fe) have performed at BL28B2 at SPring-8. The result showed that artificial cracking in the sample was clearly measured by CT and that strain maps quite correspond to CT image. Therefore, these methods are very effective tool to measure an inner state of steel material.
