| Abstract Scope |
Fitness-for-service assessment for hydrogen embrittlement has become a key research focus due to hydrogen’s expanding role in decarbonization. For components operating in gaseous hydrogen environments, testing under gas exposure is the most appropriate method, as it closely replicates service conditions. However, such testing presents challenges due to complex interactions between hydrogen and metals. Selecting an appropriate testing approach, whether in-situ or ex-situ, is critical to obtaining meaningful results.
This work presents the development of infrastructure to conduct both in-situ and ex-situ hydrogen embrittlement testing in gaseous environments. It includes a gas management system and the development of specialized setups, such as an in-situ autoclave and hollow specimen setup. Each setup introduces specific technical complexities, which are discussed. Preliminary experimental findings are presented, demonstrating the functionality of the developed systems and offering insights into hydrogen-related material behaviour. |
