Recent results of the development of the severe plastic deformation (SPD) techniques, i.e. intense plastic straining under imposed high pressure can demonstrate that bulk nanostructured metals and alloys can be successfully fabricated by this way [1]. Thorough structural characterization and investigations of unusual deformation behaviour and advanced mechanical properties, which we observed in SPD-processed materials, are presented. The structural model of nanomaterials processed by severe plastic deformation methods was developed on the basis of the obtained results. The proposed model is applied for understanding the unique properties of the nanomaterials. Several examples of applications of the SPD-produced materials are considered.
