摘要
Microstructures and microhardness have been carefully characterized for an austenitic steel deformed by High Pressure Torsion up to 16 total revolutions. A nearly idealized torsion deformation is observed even at large number of revolution. Possible reasons for deviations reported in literature between measured results and ideal torsion deformation are discussed. (C) 2004 Acta Materialia Inc. Published by Elsevier Ltd.
