We discuss hydrogen solubility and diffusion in aluminum alloyed Fe-Mn alloys. The systems of interest are deformed tetragonally and isotropically. From ab initio modelling, we obtain solution energies, then apply Oriani’s theory which reflects the influence of Al alloying as trap site diffusion. This approach is complemented by qualitative considerations based on the minimum energy paths and energy barriers for hydrogen diffusion. Both for diffusivity and solubility of hydrogen, we find that the influence of the substitutional Al atom has local chemical and volumetric and also nonlocal volumetric contributions.
