Pure nickel was subjected to severe plastic deformation by high pressure torsion in a wide interval of strains applied. Investigation was performed by means of x-ray profile analysis and residual electrical resistivity measurements at cryogenic temperatures. Concentrations of different types of defects, namely dislocation density, concentration of single and double vacancies and vacancy agglomerates has been evaluated.
