Description: Nanostructured materials, in which the structural features (e.g., grains and/or domains separated by low-angle grain boundaries) are smaller than 100nm in at least one dimension, have attracted worldwide research interest for more than a decade because of their unique properties. For example, the combination of high strength with high ductility has been reported for some nanostructured metals and alloys: this is a rare, if not impossible, combination of mechanical properties for coarse-grained metals and alloys. Among the many techniques available for producing nanostructured materials, severe plastic deformation (SPD) is the most popular and most rapidly developing one.

In recent years, bulk and graded nanometals have attracted the growing interest of materials scientists. Nanometals can be obtained by using various methods: gas condensation or ball-milling with subsequent consolidation, thermal spray techniques, annealing of thin amorphous ribbons and severe plastic deformation. The plastic deformation methods include severe torsional straining under high pressures, equal channel angular pressing, cyclic extrusion compression - and others.
