摘要：
The paper is devoted to bulk nanostructured metallic materials, produced by the severe plastic deformation (SPD) method. The authors successfully demonstrated that as a result of application of very large strains e > 10, realized at relatively low temperatures under high imposed pressures of several GPa in different metallic materials, nanostructured states in bulk billets are being formed. Under certain conditions (predominantly high angle grain boundaries, structure homogeneity) the formed nanostructured states possess unique physical and mechanical properties, in particular, simultaneous appearance of high strength and ductility (SPD paradox), low temperature and/or high rate superplasticity, etc.
