5. Conclusions Severe plastic deformation of aluminum single crystal performed by the processing with complex shearing of extruded tube (CSET) resulted in the production of the thick-wall tube with an ultra-fine-grained structure characterized by the grain size in the submicrometer range. The microstructure of the processed material at individual stages reflects the intensity of the deformation and accompanying dynamic recrystallization. The changes in the microstructure are documented by orientations of the sample localities in directions parallel to the directions of deformation.
