A new process for nano-crystalline tubes by severe plastic deformation

This paper addresses a new process of severe plastic deformation (SPD)which is suitable for extremely large shear deformation of cylindrical tubes. A mandrel is placed into the tube then an axial compression is applied on it to produce high hydrostatic pressure.
