X-ray diffraction analysis of reorientation regions formed in 111-single crystal of aluminum under compression

摘要

The paper presents results of the crystalogeometric analysis of the shear pattern formed on lateral faces of a single crystal of aluminum under compression along the direction [111]. Main features of shear strain in [111]-single crystals of aluminum have been revealed. Typical elements of strain relief have been identified and places of their location have been established. Occurrence of a bending in the crystal lattice at the macro level has been established using the Laue pattern method. The results of the X-ray analysis have been compared with the shear pattern.
