Bulk Nanostructured Materials Produced by Severe Plastic Deformation under High Pressure

摘要

Severe plastic deformation (SPD), i.e. intense plastic straining under high pressure is an innovative technique for processing ultrafine-grained nanostructured metals and alloys. Materials with nanostructures fabricated by means of SPD may display novel properties, which, however, depend strongly on the processing parameters. This paper focuses on examples of attaining enhanced mechanical properties in several metals and alloys subjected to severe plastic deformation. In addition, the relationships between processing conditions, micro structures and properties of materials produced by the SPD are considered.
