I do not agree with users Mannheim_34 and Ohnoitsjamie with their removal of any link to webpages hosted on a commercial website (almost any .com domain). I expressed my opinion here and here. I ask to the community: are these in your opinion links to " web pages that primarily exist to sell products or services, or to web pages with objectionable amounts of advertising"?
I don't want to start an edit war so if you agree with my point of view please restore any suitable reference removed [1] from this article. Thanks. -- Basilicofresco ( msg) 21:51, 18 March 2009 (UTC)
The Discovery section contained a wealth of well-researched information with several grammatical errors (English may not have been the original contributor's native dialect). I rewrote it for tighter flow and a slightly more encyclopedic tone, making sure to retain all of the original citations/data and as many of the details as possible.
The original contributors did a fantastic job researching the information and I hope they don't mind my efforts in fine-tuning the presentation of their work. - K10wnsta ( talk) 18:55, 10 September 2009 (UTC)
This article mentions Widmanstatten structures as being only in meteorites, however, Widmanstatten structures are very common in other materials as well. In the heat treatment of carbon steels, the formation of Widmanstatten structures is a common problem. In hypoeutectoid steels, the formation of ferrite Widmanstatten structures from the austenite grains occurs upon rapid cooling, whereas hypereutectoid steel form cementite Widmanstatten structures when tempered in the range of 500 degrees F for more than an hour. Nickel/aluminum bronze is another alloy known to form Widmanstatten structures. Also, Widmanstatten structures are a common feature in telluric iron. Because of this, upon its discovery in 1871 it was assumed to be meteoritic, but, by 1879, it was proven to be of terrestrial origin despite having rather coarse-grained Widmanstatten patterns. More information about Widmanstatten formation in carbon steels can be found in books like Steel Heat Treatment: Metallurgy and Technologies, Steel Heat Treatment Handbook, or scientific studies like http://www.springerlink.com/content/h402428189438068/ . Info on telluric iron can be found in books like Meteoritic Iron, Telluric Iron and Wrought Iron in Greenland, History of technology: the role of metals, Volume 6, or scientific studies like Electron microprobe analysis of terrestrial and meteoritic cohenite or http://www.minersoc.org/pages/Archive-MM/Volume_6/6-27-1.pdf . Many other sources exist as well.
It seems to me that the article should cover all aspects of Widmanstatten structures. Zaereth ( talk) 19:06, 3 October 2012 (UTC)
Would it be appropriate to add a link to the article Dendrite_(metal) here? Specifically, to my untrained eye it looks like Widmanstatten patterns are a special case of more general metallurgical dendritic growth during cooling. Olawlor ( talk) 02:18, 28 May 2019 (UTC)
@ Chiswick Chap: What's the "nice try," what's "plainly off topic," and what's the "original research"? Pattern welding and damascening, though they both result in patterned steel, are entirely different techniques. Reverting to "Pattern-welded steels such as Damascus steel" (emphasis added) thus creates an incorrect statement. The first source I added (Sword of the Nydam Type) introduced and defined the term pattern welding, while the second and third articles (Pattern-Welding and Damascening, parts 1 and 2) clarified the respective processes of pattern welding and damascening. The reverted statement is thus both incorrect and unsourced. -- Usernameunique ( talk) 19:56, 21 February 2017 (UTC)
