| Abstract Scope |
Austenitic stainless steels are essential in the hydrogen economy due to their strong resistance to hydrogen embrittlement. These steels are optimized by adjusting interstitial elements to enhance properties such as corrosion resistance and strength. However, the addition of these elements causes lattice distortions, which lead to variations in dislocation density that influence hydrogen diffusion and trapping behavior.
This study investigated the hydrogen trapping behavior in 316, 316L, and 316N austenitic stainless-steel wires with varying interstitial elements. Thermal desorption spectroscopy (TDS) was used to assess hydrogen trapping characteristics, while neutron diffraction analyzed lattice structure changes and their effect on hydrogen trapping. This combined approach offers valuable insights into hydrogen diffusion and trapping mechanisms, improving our understanding of the hydrogen embrittlement resistance in austenitic stainless steel. |
