- 20:1120:11, 6 February 2023 diff hist +1,302 Fracture resistance Not a neologism! Sorry, but someone else deleted the references to its prior use because I used other wikipedia pages as the source material. Have fixed this.
- 16:3316:33, 6 February 2023 diff hist −28 Hydrogen embrittlement Updated 'mechanism' to 'mechanisms' and minor re-wording: replace "debated" by "explored and studied".

25 August 2022
- 10:2410:24, 25 August 2022 diff hist +302 m Hydrogen embrittlement Reinstated clear distinction that molecular hydrogen does not cause embrittlement, which must have been removed by a non-metallurgist by accident.
- 10:1810:18, 25 August 2022 diff hist +41 m Hydrogen embrittlement Previous edit removed the important point that it is diffusible, atomic hydrogen that is required - not just a stress.
- 10:1210:12, 25 August 2022 diff hist −619 m Hydrogen Removed erroneous statement about pipelines and storage tanks. This is not the case. See full wikipedia article on hydrogen embrittlement. Removed ref to esoteric news item about Danish early research which is not of sufficient status or authority to appear here.
- 10:0910:09, 25 August 2022 diff hist +37 m Hydrogen misleading over-simplification amplified with correct metallurgy.
