dc.description.abstractHollow cone high-pressure torsion (HC-HPT) is proposed as a new severe plastic deformation to produce ultrafine-grained (UFG)/nanocrystalline microstructure materials. UFG Cu with an average grain size of 550 nm and well-developed high-angle grain boundary after HC-HPT of only 1 turn of torsion exhibited a high tensile strength of 414 MPa and a fracture elongation of 25%. A higher plastic deformation in the inner region, the unique deformation mode of HC-HPT, was analyzed using the finite element method. (C) 2013 Acta Materialia Inc. Published by Elsevier Ltd.
