Protection of metal interfaces against hydrogen-assisted cracking
Guillaume Hachet, Shaolou Wei, Ali Tehranchi +8
Enabling a hydrogen economy requires the development of materials resistant to hydrogen embrittlement (HE). More than 100 years of research have led to several mechanisms and model…

Segregation at prior austenite grain boundaries: the competition between boron and hydrogen
Guillaume Hachet, Ali Tehranchi, Hao Shi +8
The interaction between boron and hydrogen at grain boundaries has been investigated experimentally and numerically in boron-doped and boron-free martensitic steels using thermal d…

Microstructural features and hydrogen diffusion in bcc FeCr alloys: a comparison between the Kelvin probe- and nanohardness based- methods
Jing Rao, Binhan Sun, Arulkumar Ganapathi +6
Hydrogen embrittlement can result in a sudden failure in metallic materials, which is particularly harmful in industrially relevant alloys, such as steels. A more comprehensive und…
