The origin of topological anisotropy in silica glass
Did you ever wonder on the origin of the atomic-scale structural anisotropy in silica glass, induced by deformation? Our article published this summer in Acta Materialia is bringing some answers: Ganisetti et al., The origin of deformation induced topological anisotropy in silica glass, Acta Materialia 257 (2023) 119108 [open access]. I am particularly happy to share this wonderful piece of work mainly performed at the Institute for Material Science and Engineering (FAU Erlangen-Nürnberg, Germany) by Dr. Sudheer Ganisetti who has been briefly member of my group last year.
To COMPLAS 2023 in Barcelone
I will be at the COMPLAS conference in Barcelone, 5-7 September 2023, alonside with Djafar IABBADEN an several colleagues from the LEM3. The COMPLAS conferences started in 1987 and since then have become established events in the field of computational plasticity and related topics.
Welcome to Abdallah
I am glad to welcome Abdallah WAZNE in my group as research engineer (ingénieur de recherche). He will work on the Segregation at Interfaces in Lightweight Alloys towards Tailored Mechanical Properties, within the framework of the ANR-DFG SILA in collaboration with RWTH Aachen in Germany.
Welcome to Djafar
I am glad to welcome Djafar IABBADEN in my group as Postdoctoral researcher. He will work on the atomistic fundamentals of plasticity at interfaces in lightweight complex alloys and transfer to continuum models, within the framework of the ANR JCJC ATOUUM.
How does synchro-Shockley dislocations propagate? Our new article is out in Scripta Materialia
How does synchro-Shockley dislocations propagate in Laves phases? As published in Scripta Materialia with the title "Thermally activated nature of synchro-Shockley dislocations in Laves phases", we evidenced the different mechanisms responsible for a kink-pair-type propagation sensitive to temperature. More details in Xie et al., Scripta Materialia 235 (2023) 115588. Manuscript freely available on HAL.
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.
