My understanding of at least the conventional thinking of hydrogen embrittlement of irons has to do with internal dislocations and vacancies in the iron. The hydrogen can penetrated iron in its neutral monatomic form but cannot as H2. When the hydrogen gets loaded into the iron as a monatomic species and encounters a void/dislocation/vacancy, it may hang around in there long enough for it to encounter another monatomic hydrogen and then it forms an H2 molecule. The H2 molecule cannot escape. Eventually more and more H2 molecules are formed in the void and it becomes high pressure, putting a great deal of stress on the lattice causing the embrittlement.
In the UHD form, the hydrogen would simply escape from the void; and thus, UHD would seem to be counter to that which I think of as embrittlement of iron. Also, keep in mind that most FexOy catalysts are formed as fine oxide (+ alkali) particles that are agglomerated into a larger, but highly porous body. These are not like rust on an iron slug. The whole idea is for H2 to be able to breathe through the material. On Wed, Jan 20, 2016 at 7:50 AM, Teslaalset <[email protected]> wrote: > Good point.
