Quantitative evaluation of hydrogen segregation at tilt grain boundaries and dislocations in Fe–Cr–Ni alloy

Hydrogen interactions with microstructural defects play a critical role in hydrogen-induced degradation of austenitic stainless steels, yet a quantitative description of hydrogen solubility across defects of different dimensionalities remains limited. This work combines a machine learning interatomic potential with gra...
