4. Conclusion
The development of a hydrogen transport or storage infrastructure requires better control and quantification of the mechanical behavior of materials to guarantee a high level of safety and acceptable costs.
This requires a thorough understanding of experimental conditions, as the material's susceptibility to hydrogen embrittlement will depend on microstructural factors at various scales (phases, grain boundaries, precipitates, traps, dislocations, gaps), mechanical stresses (monotonic, cyclic) and the environment (pressure, temperature, impurities). This is further exacerbated in the presence of a defect (stress concentration or crack). Various embrittlement indices are proposed in the literature, depending on the mechanical parameter measured (elongation at break, cross-section reduction, toughness, crack propagation speed, burst pressure, etc.). These indices...
