I think hydrogen embrittlement is thought to be merely the accumulation of H gas at grain boundaries of the steel and the resulting internal stress that results. That is why heat treating steel after welding using anything that can form hydrogen, especially damp electrodes, always needs to be done to drive the H gas out of the welded area. I doubt embrittlement has anything to do with UDH.

Embrittlement could indeed be coupled to UHD.

That is because there are known problems with hydrogen, besides cost. The main reason for using carbon is that coal and coke is extremely cheap – and it takes a lot of it, but hydrogen when present tends to cause “hydrogen embrittlement” in iron, which could be related to UDH. In fact, coke is used instead of coal because it has no hydrogen content. Embrittlement, in severe cases is related to long time exposure to hydrogen, and this could indicate that some of the damage is being caused by UDH, as it densifies and penetrates. IOW, any hydrogen exposure to iron causes problems – and the longer the exposure, the worse the problem. From: Teslaalset Ø wouldn't that have caused numeral problems at traditional production of magnetite using 3Fe2O3 + H2 → 2Fe3O4 +H2O, assuming UDH can be made in a similar manner ? Holmlid indicated in one of his papers that UDH can be formed as well using Shell 105 catalyst. The “leap of faith” and it is large… is that in a matrix of iron-oxide, loaded with pressurized deuterium which is absorbed (and is bosonic) there will be an continuous oscillation and change in volume of the nanopores, when hematite changes to magnetite and back again – and this oscillation will create shock waves which are comparable at that small geometry, to what Holmlid sees with laser pulses. These would occur at IR frequencies in a heated pressure vessel, which is also magnetized. Because of the IR, there could be a plasmonic effect. The nano shock waves would be combined with large changes in local magnetism, as the phase shifts from ferromagnetic ordering to antiferromagnetic rapidly. There is likely to be a contribution from DCE – the dynamical Casimir effect.
