Developing SPD Methods Processing Bulk Nanostructured Materials with Enhanced Properties

Severe plastic deformation (SPD), I.e. intense plastic straining under high pressure, is an innovative technique for processing ultrafine-grained nanostructured metals and alloys. SPD fabricated nanostructures can lead to novel properties, which, however, depend strongly on the processing parameters...

Description
Summary:Severe plastic deformation (SPD), I.e. intense plastic straining under high pressure, is an innovative technique for processing ultrafine-grained nanostructured metals and alloys. SPD fabricated nanostructures can lead to 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 among the processing conditions, microstructures and properties of the materials produced by SPD are considered.
