Complementary use of transmission electron microscopy and atom probe tomography for the investigation of steels nanostructured by severe plastic deformation
- X. Sauvage, W. Lefebvre, C. Genevois, S. Ohsaki, K. Hōno
- Materials Science
- 1 June 2009
The properties of bulk nanostructured materials are often controlled by atomic-scale features such as segregation along defects or composition gradients. Here we discuss the complementary use of… Expand

Fabrication of Bulk Metallic Glass Sheet in Cu-47 at% Zr Alloys by ARB and Heat Treatment
Pure Cu (99.96%) and pure Zr (99.8%) sheets were stacked and severely deformed up to equivalent strain of 16 by the accumulative roll bonding (ARB) process conducted at RT. The ARB processed sheets… Expand
