The orientation contrast at the head of slip bands at a grain boundary was studied by a modified Schulz technique. The images on the topographs were simulated using kinematical intensity calculations. The stress field of the macrodislocation, which represents the head of the slip band, includes the surface stress relaxation. The Burgers vectors of the macrodislocations were determined.
