Effect of severe plastic deformation on structure and mechanical properties of pure aluminum and AlMnFe alloy

The results of the hardness measurements, three-point tests and X-ray diffraction studies of the samples consisted of 12 aluminum foils or of two rapidly cooled Al95.8Mn3.8Fe0.4 ribbons consolidated by high pressure torsion processing, are presented. It is established that the structural changes caused by severe deformation results in essential increase of strength of the consolidated samples combined with accepted level of plasticity.
