| Abstract Scope |
Hydrogen is one of the most promising ways of ensuring a transition from traditional fossil fuels to more sustainable, low-carbon alternative energy solutions. Among metallic materials, austenitic stainless steels are commonly used for hydrogen applications due to their low sensitivity to hydrogen embrittlement. However, these steels cannot be considered immune to this phenomenon. Hydrogen effect on cyclic plasticity behavior represents a critical issue for fatigue design since constitutive behavior are mandatory to assess global and local mechanical response of structures.
This study is focused on the hydrogen effect on cyclic creep behavior of AISI 310S stainless steel and more specifically on the study of ratchetting in hydrogen environments. This work illustrates the influence of hydrogen on cyclic creep behavior and its consequences on dislocations behavior thanks to TEM observations. The impact of hydrogen on cyclic behavior is discussed in relation with the evolution of internal stresses, dislocations organization. |
