Abstract
This work is focused on research of mechanical propeties of metastable nano structured alloys processed by severe plastic deformation (SPD). The emphas is has been on the study of structure and deformation behaviour at elevated temperatures in intermetallic Ni3Al and Al 1420 alloy. The processed nanos tructured alloys exhibit enhanced superelasticity at high strain rate or lo w temperature as compared to microcrystalline alloy. Specific features of s uperplastic behaviour in nanostructured alloys and the requirements to achi eve enhanced superplasticity are discussed. (C) 2001 Elsevier Science B.V. All rights reserved.
