Journal ArticleDOI
Elementary mechanisms of shear-coupled grain boundary migration.
Armin Rajabzadeh,Armin Rajabzadeh,Frédéric Mompiou,Frédéric Mompiou,Marc Legros,Marc Legros,Nicolas Combe,Nicolas Combe +7 more
TL;DR: A detailed theoretical study of the elementary mechanisms occurring during the shear-coupled grain boundary (GB) migration at low temperature is performed focusing on both the energetic and structural characteristics.
Journal ArticleDOI
Evidence of grain boundary dislocation step motion associated to shear-coupled grain boundary migration
TL;DR: In this article, the authors reported dynamical observations of the grain boundary-mediated plasticity during in situ transmission electron microscopy straining experiments at moderate temperature (400 C) both in a 76.4 bicrystalline and a polycrystalline Al sample.
Journal ArticleDOI
The role of disconnections in deformation-coupled grain boundary migration
Armin Rajabzadeh,Armin Rajabzadeh,Frédéric Mompiou,Frédéric Mompiou,Sylvie Lartigue-Korinek,Nicolas Combe,Nicolas Combe,Marc Legros,Marc Legros,Dmitri A. Molodov +9 more
TL;DR: In this paper, the authors considered that GB migration under stress can occur both due to the motion of pre-existing disconnections and due to disconnections resulting from decomposition of lattice dislocations interacting with the GB.
Journal ArticleDOI
Fully Crystalline Faceted Fe–Au Core–Shell Nanoparticles
Cyril Langlois,Patrizio Benzo,Raul Arenal,Magali Benoit,Julien Nicolaï,Nicolas Combe,Anne Ponchet,Marie-José Casanove +7 more
TL;DR: Fe-Au core-shell nanoparticles displaying an original polyhedral morphology have been successfully synthesized through a physical route and are attributed to the weak elastic energy resulting from the low misfit at the Fe/Au (100) interface compared to the surface energy contribution.
Journal ArticleDOI
Disconnections kinks and competing modes in shear-coupled grain boundary migration
TL;DR: In this paper, the response of small-grained metals to mechanical stress is investigated by a theoretical study of the elementary mechanisms occurring during the shear-coupled migration of grain boundaries (GB).
