New article on synchro-Shockley dislocations in Physical Review Materials
Our last work "Unveiling the mechanisms of motion of synchro-Shockley dislocations in Laves phases" as just been published in Physical Review Materials. In collaboration with the RWTH Aachen, we demonstrate that nucleation and propagation of kink pairs is the energetically favorable mechanism for the motion of the synchro-Shockley dislocation. Additionally, we identified a mechanism of nonsequential atomic shuffling for the motion of such dislocation. More detail on Xie et al., Physical Review Materials 7 (2023), 053605. Manuscript freely available on HAL.

New article on the plasticity of TCP phases accepted in Advanced Materials
I am gald to announce that our new article "Tailoring the Plasticity of Topologically Close-Packed Phases via the Crystals’ Fundamental Building Blocks" is now published in Advanced Materials in open access. This work is the result of a large collaboration led by RWTH Aachen (DE), involving the MPIe (DE), the Pprime institute (FR) and myself.
Awarded the Jean Morlet prize by the SF2M and Aperam
I am most proud to have been awarded the Jean Morlet prize by the SF2M (Société Française de Métallurgie et de Matériaux) and Aperam. This prize is the recognition of my work on the modeling of the behavior of metallic materials towards the design of property-by-design innovative alloys. I would like to thanks all my collaborators around de world that have contributed to this achievment.

Welcome to Joé!
I am glad to welcomeI Joé PETRAZOLLER in my group as PhD student. He will work on the atomistic simulation and micromechanical modeling of chemo-mechanical couplings in the presence of crystal defects under the supervision of Thiebaud RICHETON, Stéphane BERBENNI and myself. We are very gratefull to the support of the Université de Lorraine and the French Ministry of Research.
