Abstract

Hydrogen energy is expected to solve both the lack of fossil fuel resources and carbon dioxide emission. In order to develop the hydrogen society, it is urgent matter to establish the strength evaluation method for the components exposed to hydrogen in machines and structures, such as fuel-cell vehicles and infrastructures, because hydrogen has been reported to degrade the strength of materials [1,2]. Our previous study as in Fig. 1, on a type 304 austenitic stainless steel which is a candidate for use in hydrogen environment shows that the fatigue crack growth rate under the hydrogen gas environment is higher than that under air atmosphere in the range of high growth rate.
