Laurent BRIOTTET

Dr. hab., CEA Fellow​

DrHab Laurent Briottet is Fellow at CEA leading activities dedicated to Hydrogen Embritlment of metallic materials under hydrogen gas.

Starting with a Material Science background, he made his PhD at EMSE on the modelling of void growth in metallic materials. He spent one year at McGill University (Montreal, Canada) as a post doctoral fellow, studying the mechanical behaviour of two-phase materials.

In 2012, he obtained his habilitation to conduct research addressing embrittlement of metallic materials.​

Research Description​​

Laurent Briottet works on the mechanical behaviour and damage of metallic materials, linking microstructure and macroscopic behaviour. For the past 15 years, he has been studying hydrogen gas embrittlement of metal alloys under pressure.

This has necessitated the acquisition and development of specific experimental equipments to test the mechanical behaviour of metallic materials at pressures up to 1000 bar.

The results obtained provide a better understanding of the mechanisms involved, quantify the effects of H2 to facilitate the design of hydrogen infrastructures and provide the data needed to develop more appropriate standards.​
