Xavier Feaugas

Xavier Feaugas is a Professor and Teacher-Researcher at the University of La Rochelle, serving as Director of the Laboratory of Engineering Sciences for the Environment (LaSIE) UMR CNRS 7356. His work spans the Research Section CNU 28 and CNRS Scientific Department INSIS, focusing on fundamental mechanisms of material degradation in demanding environments.

His research centers on the critical intersection of plasticity mechanisms and surface reactivity, with particular emphasis on hydrogen embrittlement and stress corrosion cracking. Key interests include:

• Hydrogen diffusion and trapping in heterogeneous microstructures
• Metallurgical state effects on hydrogen-assisted failure
• Multiphysical couplings at liquid/solid interfaces
• Nanoscale void stability under hydrogen exposure
• Corrosion-fatigue interactions in advanced alloys

Feaugas' recent publications reveal a strong trend toward multi-scale experimental and computational approaches, combining electrochemical techniques (SECM), in-situ characterization, and advanced modeling to unravel hydrogen transport phenomena. His work spans high-impact journals across materials science, corrosion engineering, and physical metallurgy, demonstrating consistent leadership in hydrogen-related failure mechanisms.

As Director of LaSIE, he oversees research on engineering sciences for environmental applications, fostering collaborations across French and international institutions. His laboratory integrates experimental facilities for hydrogen charging, electrochemical analysis, and microstructural characterization to address industrial challenges in energy and transportation sectors.
