Summary

This paper describes first attempts to apply the method to characterize the deformation state ahead of the tip of a bending-loaded crack. In this case the damage structure is very inhomogeneous. Consequently, a steep gradient of the defect structure occurs there. The investigation of structures with nanoscaled defects under such gradients is methodically very challenging. The development of high-intensive and high-brilliant X-ray sources like synchrotron facilities of the third generation, however, provides a suitable approach by using a microfocused beam and shifting the sample point by point through the beam. The method is named scanning microbeam SAXS (SM-SAXS) and is presented in following study.
