In this study, constrained groove pressing (CGP) and high pressure torsion (HPT) processes as
effective methods of severe plastic deformation (SPD), for strain imposed on the pure copper were used. This paper presents the results of an experimental research, to review the influence of CGP and HPT processes on the mechanical properties, Hardness and tensile tests on copper samples of HPT and CGP has been done. Results of HPT Process showed that hardness in the radial direction is variable and away from disk center in the radial direction continuously increases. Of course, in higher pressing steps the slight decrease in strength and hardness is observed, the full explanation is given in this paper. Finally, comparison results of two methods, their advantages and limitations of them are studied.
