What is Superalloy?
[[File:Turbinenschaufel RB199.jpg|thumb|295x295px|Used blade of a [[jet aircraft]] engine. This blade is made of a [[Nickel]]-based superalloy.]] A '''superalloy''', or high-performance [[alloy]], is a [[metal]] alloy that has several key [[wikt:characteristic|characteristic]]s. These include excellent [[wikt:resistance|resistance]] to high [[temperature]]s and [[corrosion]] or [[oxidation]].<ref>{{cite web |url=https://www.nickelinstitute.org/NickelUseInSociety/MaterialsSelectionAndUse/Ni-ContainingMaterialsProperties/HighNickelAlloysAndSuperalloys.aspx |title=High Nickel Alloys & Superalloys |publisher=The Nickel Institute |access-date=6 October 2016 |archive-date=27 November 2015 |archive-url=https://web.archive.org/web/20151127133644/http://www.nickelinstitute.org/NickelUseInSociety/MaterialsSelectionAndUse/Ni-ContainingMaterialsProperties/HighNickelAlloysAndSuperalloys.aspx |url-status=dead }}</ref> The term was first used after [[World War II]].<ref>{{cite web |url=http://www.tms.org/meetings/specialty/superalloys2000/superalloyshistory.html |title=Superalloys: A Primer and History |publisher=The Minerals, Metals and Materials Society (TMS) |access-date=6 October 2016}}</ref> They were developed for use in [[jet engine]]s and [[gas turbine]]s.<ref name=AZO>{{cite web |url=http://www.azom.com/article.aspx?ArticleID=1412 |title=Superalloys - An Introduction |date=14 May 2002 |website=AZO Materials |publisher=AZoNetwork Ltd |access-date=6 October 2016}}</ref> About 75[[%]] of superalloys are used in [[aerospace engineering]].<ref name=AZO/> == References == {{reflist}} {{Technology-stub}} [[Category:Alloys]]
