For nearly twenty years now, the academic – and increasingly industrial – world has been interested in new classes of metallic alloys. HEA (high entropy alloys), which are concentrated, single-phase alloys based on several metallic elements and whose Cantor alloy (Co20Cr20Fe20Mn20Ni20) is the archetype, were quickly supplemented by multiphase alloys, CCA (complex concentrated alloys) or MPEA (multi principal elements alloys) in which secondary phases bring improvements in properties.
Atom Probe Tomography (APT) enables access to compositional, morphological and structural information from microstructural features at the atomic scale. This information is especially important on neutron-irradiated material to characterize chemical composition variations around...
In the context of fast neutron reactors, boron carbide is a ceramic material with excellent properties for controlling nuclear reactor power. Thanks to its high absorption cross sections of 10B, this material provides an excellent neutron absorber. As a consequence of the 10B(n,α) nuclear reactions, significant quantities...
Synchrotron X-rays provide ideal tools for studying the processes that control localised corrosion of metals in wet environments, which is key to understanding the processes that can cause damage to structures such as nuclear waste storage containers and aircraft. In this talk, the morphology of localised corrosion is...
At the beginning we will have a brief look at the liquid-glass transition phenomenon. However, most attention will be focused on the behavior of molecular dynamics during the vitrification process, caused by cooling and compression. Molecular dynamic behavior will be analyzed and...
Hybrid ab initio-machine learning simulatio
The ever increasing power of digital computers and the maturity of atomistic simulation tools based on first principles calculations and molecular mechanics provide a unique opportunity to design new materials for engineering applications in silico. The main limitation is...
