Talk:Peening

Hello- Here's an excellent article that describes peening and the state-of-the-art extremely well. http://www.americanheritage.com/articles/magazine/it/2007/3/2007_3_51.shtml

Improving fatigue life
The wikipedia peening article makes no mention of peening for enhancing fatigue life, arguably the most successful application of the process. —The preceding unsigned comment was added by 67.112.207.58 (talk • contribs).

Older history?
The article suggests that the idea itself is historically recent, dating only from the onset of the 20th century. I recall reading a magazine article (I believe it was in American Heritage or some other history of tech source) which identified the idea as possibly dating back to the creation of Damascus steels -- it argued that peening was a part of the lost art of making such steels. Someone might want to investigate this for inclusion. —Preceding unsigned comment added by 24.250.253.251 (talk) 10:11, 24 July 2010 (UTC)


 * Agreed. The article cited (Fuchs/Cary) only refers to shot peening, so something on the far longer history of peening itself is needed here. Hope to come up with something for inclusion after I've done some research. CSK45Kays (talk) 15:22, 12 October 2023 (UTC)

Laser Peening
This article states that laser peening is NOT a cold work process. Cold working is essentially strain hardening. The surface is plastically deformed to impart a layer of compression. Laser peening does just that so I just don’t see why it’s a “notable exception”. Perhaps I’m wrong or misunderstanding a concept? For now I’m going to add a citation needed tag.

 * While I don't know the answer to your question, I agree with your logic and think that there's a misunderstanding. Wizard191 (talk) 15:47, 14 January 2011 (UTC)

It seems it can be a cold working or a heat treating process depending on the application. See e.g. https://www.lsptechnologies.com/resources/laser-peening-vs-laser-hardening/. CSK45Kays (talk) 14:37, 7 January 2022 (UTC)

Photo Hearst Building
It really bothers me that this photo is placed in such a prominent position on both this page and the Shot Peening page. Has nothing to do with the content of the article and suggests that peening is a common practice for surface finishing on buildings. As mentioned above, the most common use is to combat metal fatigue. CSK45Kays (talk) 16:25, 3 February 2022 (UTC)

Traditional technique or new discovery?
The sharpening blades section says "Scythe and sickle blades have traditionally been sharpened by occasional peening," but the history section says peening was discovered circa 1910. Given that scythes and sickles have been used since earliest human recorded history, there is a discrepancy: either "traditional" hand tool sharpening didn't start until after 1910, or peening has been practiced (perhaps without understanding its metallurgical implications) for far longer. 2603:800C:1501:FA3D:D916:EA47:C093:F8D9 (talk) 05:48, 3 March 2023 (UTC)


 * See my comment on Older History above. So more info on the history of peening is needed. CSK45Kays (talk) 15:26, 12 October 2023 (UTC)
 * I have drafted a couple of paragraphs on peening history in my sandbox which I'd like to insert at the beginning of "History".
 * I'd delete the reference to the Barker Dam - doesn't really fit here and the link doesn't work anyway - as well as the first sentence of the second paragraph ("first published article"), which is not strictly speaking accurate.
 * Would welcome any comments. CSK45Kays (talk) 11:46, 9 November 2023 (UTC)
