Application of X-ray diffraction topography for the study of Al single crystals plastically deformed at low temperatures

The Lang method has been used to investigate regularities and peculiarities of formation of Al single crystal dislocation structure in various stages of the stress-strain curve at 77.3 and 4.2°K up to high strains. The low temperature deformation of crystals has been found to cause a sharp localization of the deformation into slip bands that correspond to different glide systems. A comparison with metallography is added.
