Severe plastic deformation has become a popular method for processing ultrafinegrained microstructures. The most widely used deformation methods are: equal channel angular pressing (ECAP), torsion under compression (TUC) and multi-step forging (MSF). Large plastic strain may also be achieved by a hydrostatic extrusion which results in ultrafine and homogenous structure in the entire volume of the material. The aim of this work was to show that hydrostatic extrusion can be used to obtain nanostructured materials.
