PhD in Hydrogen Storage and Mechanical Behavior of Ti-Nb-Zr-Ta-Mo HEA Alloy Université Sorbonne Paris Nord in France

PhD opening at Université Sorbonne Paris Nord (LSPM-CNRS / École doctorale Galilée) on the characterization of hydrogen storage capacities of a model high-entropy alloy (HEA), specifically a Ti-Nb-Zr-Ta-Mo alloy. The project studies how hydrogen affects hydridation, microstructure, diffusion kinetics, and the mechanical behavior of the alloy.

The research is strongly interdisciplinary and combines materials science, mechanical behavior, hydrogen storage, hydrides, and microstructural characterization. Planned work includes characterization of the as-received alloy, hydrogen charging/discharging cycles, measurement of hydride formation and size distribution, microstructural and mechanical analysis of hydrogen-charged samples, and studying the effect of loading conditions and temperature on hydrogen absorption and mechanical response.

The post mentions access to LSPM and MECAMAT expertise and equipment, including SEM/EBSD, XRD, DSC, catharometry, high-pressure/high-temperature hydrogen loading, and tensile testing under hydrogen and at temperature. The project is linked to broader interest in hydrogen storage materials and may also connect to biomedical applications because the alloy is described as having good biocompatibility and low elastic modulus.

Eligibility: Master’s student or engineering graduate in materials science, with a background in materials characterization and knowledge of mechanical behavior and material structure. Interest in multidisciplinary processes is a plus.

Funding: ministerial PhD allocation for 2026–2029.

Application: send a CV, cover letter, and transcripts from the most recent year of study to the PhD supervisor and co-supervisor.
