Harmonic structure, a promising microstructure design Open
The harmonic structure is a recently introduced concept paving the way for engineering metallic materials to achieve excellent mechanical performance. They consist of soft coarse-grained regions (Core) that are three-dimensionally surround…

Deformation Mechanisms of Zirconium Alloys after Irradiation Studied by Dislocation Dynamics Simulations and In Situ Straining Experiments in TEM Open
Zirconium alloys, used in the nuclear industry, are subjected to neutron irradiation that affects their mechanical properties. At the microscopic scale, neutron irradiation creates small dislocation loops that act as obstacles against disl…

Shear-coupled migration of grain boundaries: the key missing link in the mechanical behavior of small-grained metals? Open
Grain size reduction is a very efficient way to block dislocation movements and therefore create very strong metals and alloys. Not only grain boundaries are known obstacles for dislocations, but when reaching nanometer dimensions, crystal…

<i>pycotem</i>: An open source toolbox for online crystal defect characterization from TEM imaging and diffraction Open
We present a series of tools working together that facilitate the determination of dislocation Burgers vectors and slip planes, interface plane normals and misorientation between two crystals from a series of Transmission Electron Microsco…

3D nanostructural characterisation of grain boundaries in atom probe data utilising machine learning methods Open
Boosting is a family of supervised learning algorithm that convert a set of weak learners into a single strong one. It is popular in the field of object tracking, where its main purpose is to extract the position, motion, and trajectory fr…

Atomic scale analyses of {\bb Z}-module defects in an NiZr alloy Open
Some specific structures of intermetallic alloys, like approximants of quasicrystals, have their unit cells and most of their atoms located on a periodic fraction of the nodes of a unique {\bb Z}-module [a set of the irrational projections…
