Abstract :
Deformation around two scratches in Alloy 600 (A600) was studied nondestructively using synchrotron Laue differential aperture X-ray microscopy. The orientation of grains and elastic strain distribution around the scratches were measured. A complex residual deviatoric elastic strain state was found to exist around the scratches. Heavy plastic deformation was observed up to a distance of 20 μm from the scratches. In the region 20–30 μm from the scratches the diffraction spots were heavily streaked and split indicating misoriented dislocation cell structures.
