Iron whiskers with [111] growth direction were subjected to a tensile stress and simultaneously observed by X‐ray transmission topography. The initiation of the deformation occurred in the part of the whisker which revealed grown‐in lattice defects. The distorted area propagated not only as a result of increasing the tensile stress but also during its relaxation at constant elongation. The dislocations introduced during the deformation were of the same type as grown‐in dislocations. Increasing the stress led to a non‐uniform rotation of the crystal lattice during the deformation. The axis of rotation was found to be [33] for one whisker and [111] for another one.
