Severe Plastic Deformation (SPD) is a very effective method to produce bulk nanostructured metals , under conditions of enhanced hydrostatic pressure and/or of a relatively low deformation temperatures. Such a heavy plastic deformation produces several crystal lattice defects like dislocations, grain boundaries, and also vacancies. In comparison with conventional cold work techniques, SPD methods achieve a much higher concentration of vacancies .
