Complementary use of transmission electron microscopy and atom probe tomography for the investigation of steels nanostructured by severe plastic deformation
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 ofExpand
