Two aspects are of primary interest here: first, the local arrangement of the hydrogen atoms in the interstitial sites in different environments of iron, manganese, and aluminum, to find a site preference for the hydrogen; second, the dependence of the solubility on mechanical deformation conditions, in particular for pure volume changes due to isotropic straining and for volume-conserving tetragonal distortions.
