This paper provides an introduction in the field of severe plastic deformation (SPD). First of all the main methods to produce SPD materials are discussed. In the following section, the mechanisms leading to the formation of fine grains are reviewed and the influence of changes in strain path is highlighted. During post-SPD thermal annealing, some typical microstructural changes take place. The influence of SPD and subsequent annealing on strength, ductility and superplastic properties are reviewed. Finally the paper provides a short overview of fatigue resistance and corrosion properties of t

Abstract:
Severe plastic deformation (SPD) can lead to the phase transformations in the materials. Even the SPD-treatment at ambient temperatureTSPD= 300 K is frequently equivalent to the heat treatment at a certain elevated temperature (effective temperature)Teff> 300 K. However, if the real annealing at effective temperature leads to the grain growth, SPD leads to strong grain refinement. SPD also accelerates the mass transfer in the materials. In this review the methods of determination for effective temperature after high-pressure torsion of metallic alloys are discussed as well as SPD-driven acc

Severe plastic deformation (SPD) techniques are the best for producing of massive nanostructured materials. The methods of equal channel angular pressure (ECAP) and twist extrusion (TE) are realized by simple shear uniform deformation without change of cross-section sizes of sample. In the case of roll forming (RF) the shear strain is localized in the near-surface layer of metal. Intensity of shear strain in the near-surface layer depends on variation of parameters of deformation and conditions of friction in a contact.

Abstract:
Severe plastic deformation (SPD) techniques have now successfully been applied to fabricate a large number of nanostructured metals and alloys. Most studies have so far focused on fcc materials, although some studies on Ti and Mg also exist. In this work we describe the nanostructures resulting from processing pure Zr by high pressure torsion (HPT) and accumulative roll bonding (ARB).
