In recent years, bulk nanostructured materials (NSM) processed by methods of severe plastic deformation (SPD) have attracted the growing interest of specialists in materials science [1]. This interest is conditioned not only by unique physical and mechanical properties inherent to various nanostructured materials, eg processed by gas condensation [2, 3] or ball milling with subsequent consolidation [4, 5], but also by several advantages of SPD materials as compared to other NSM. In particular, SPD methods resulted in overcoming of a number of difficulties connected with residual porosity in compacted samples, impurities from ball milling, processing of large scale billets and practical application of the given materials. The principle of processing of bulk nanostructured materials using SPD methods is an alternative to the existing methods of nanopowder compacting. It is well known that heavy deformations, for …
