Measurements of lattice distortion due to a slip band were carried out and compared with the theoretically estimated values. A simple model of a single‐slip system with uniformly distributed dislocations in a narrow planar slip band was adopted. It was shown that both the effect of all dislocations in the slip band and the surface relaxation must be taken into account.
