Residual stress measurement is important to understand Stress Corrosion Cracking process. In this study, measurements of imaging and inner stress mapping around a crack-tip in steel material (alpha-Fe) have performed at beam-line BL14B1 and BL28B2 at SPring-8. The results showed that artificial cracking in the sample was clearly measured by imaging and that stress maps quite correspond to the result of imaging. Therefore, these methods are very effective tool for measurement of inner state of steel material.

Austenitic stailess steel consist of large grains about 50 to 100 
m in size. Therefore, it is difficult to measure strain of the steel using X-ray diffraction. In this study, a new analysis method applied to X-ray profiles of the steel by using synchrotron white X-ray. The results showed that average strain mapping of austenitic Fe(311), (420), (620), which are similar Young modulus, was suitable to predicted that, althogh strain mappings by using single planes were not reasonable. This suggested that it would be possible to measure strains in small area, for example crack tips, at austenitic stainless steel.

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.
