A new severe plastic deformation process based on conventional high pressure torsion is introduced. The process, called planar high pressure torsion (P‐HPT), is capable of inducing large shear strains into materials with planar geometries, such as sheets or strips and can basically be implemented on every standard HPT machine. The principles of this technique will be presented and accompanied by a case‐study, where P‐HPT will be applied on a sheet of pure copper with dimensions of 220 × 110 mm 2 and a thickness of 0.75 mm. For comparison, the material is deformed by conventional high pressure torsion using standard specimens with a diameter of 8 mm as well. It will be shown that the mechanical properties and microstructure obtained by P‐HPT correspond well to conventional high pressure torsion results.
