Severe Plastic Deformation Methods for Bulk Nanostructured Materials

Several new SPD methods for bulk nanostructured materials, such as Equal Channel Angular pressing, High Pressure Torsion, Multi-forging, Multi-axial Compression, Severe Cold-rolling of lath Martensite, Accumulative Roll-bonding,Cold Drawing and Repetitive Corrugation and Straightening are reviewed in this paper.The microstructure characteristics of bulk nanostructured SPD materials are analysed. Emphasis is placed on advances in SPD methods.
