Atomic scale characterization of the nucleation and growth of SnO2 particles in oxidized CuSn alloys
Megha Dubey, Xavier Sauvage, Fabien Cuvilly +2
The internal oxidation of Sn was investigated to understand the oxidation kinetics of monophase CuSn alloys. SnO2 particles were characterized by analytical transmission electron m…
Grain boundary segregation in UFG alloys processed by severe plastic deformation
Xavier Sauvage, Artur Ganeev, Yulia Ivanisenko +3
Grain boundary segregations were investigated by Atom Probe Tomography in an Al-Mg alloy, a carbon steel and Armco\trademark Fe processed by severe plastic deformation (SPD). In th…
Atomic scale investigation of Cr precipitation in copper
Abdelahad Chbihi, Xavier Sauvage, Didier Blavette
The early stage of the chromium precipitation in copper was analyzed at the atomic scale by Atom Probe Tomography (APT). Quantitative data about the precipitate size, 3D shape, den…
Homogeneous Cu-Fe super saturated solid solutions prepared by severe plastic deformation
Xavier Quelennec, Alain Menand, Jean Marie Le Breton +2
A Cu-Fe nanocomposite containing 50 nm thick iron filaments dispersed in a copper matrix was processed by torsion under high pressure at various strain rates and temperatures. The…
