The steels are microalloyed with niobium and niobium\u2013vanadium (Nb\u2013V), respectively, and produced by continuous hot rolling. Besides the precipitates TiN and (Ti, Nb) (C, N), which were 10\u2013100 nm in size, a large number of precipitates smaller than 10 nm distributed in the two steels have been observed. In the Nb\u2013V microalloyed steel, only a few titanium nitrides covered by vanadium compounds on the surface have been observed. It is inferred that the vanadium exists mainly in the matrix as a solid solution element. The fact has been accepted that there was no contribution to the precipitation strengthening of the X80 steel by adding 0.04\u20130.06% vanadium under the present production process. By contrast, the toughness of the Nb\u2013V steel is deteriorated. Therefore, a better toughness property of the Nb microalloyed X80 results from the optimum microalloying composition design and the suitable accelerating cooling after hot rolling.<\/jats:p>","DOI":"10.1017\/s1431927613012348","type":"journal-article","created":{"date-parts":[[2013,8,6]],"date-time":"2013-08-06T13:09:27Z","timestamp":1375794567000},"page":"62-65","source":"Crossref","is-referenced-by-count":4,"title":["Precipitates in Nb and Nb\u2013V Microalloyed X80 Pipeline Steel"],"prefix":"10.1093","volume":"19","author":[{"given":"Zhongyi","family":"Li","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Delu","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jianping","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenhuai","family":"Tian","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2013,8,6]]},"reference":[{"key":"S1431927613012348_ref002","doi-asserted-by":"publisher","DOI":"10.1080\/09500830701427003"},{"key":"S1431927613012348_ref003","first-page":"20","article-title":"Occupying tendentiousness of niobium in \u03b3-Fe and its effect on grain boundary","volume":"33","author":"Shang","year":"2003","journal-title":"Sci China (Ser E)"},{"key":"S1431927613012348_ref006","first-page":"61","article-title":"Causes and effects of nitride and carbonitride precipitation during continuous casting","volume":"16","author":"Turkdogan","year":"1989","journal-title":"Iron Steelmaker"},{"key":"S1431927613012348_ref007","first-page":"207","article-title":"Influence of coiling temperature on precipitate and property of X80 pipeline steel","volume":"9","author":"Wang","year":"2010","journal-title":"J Mater Metall"},{"key":"S1431927613012348_ref008","first-page":"395","volume-title":"The Second Phase in Steel Material","author":"Yong","year":"2006"},{"key":"S1431927613012348_ref009","first-page":"47","volume-title":"The Second Phase in Steel Material","author":"Yong","year":"2006"},{"key":"S1431927613012348_ref010","first-page":"75","article-title":"Process, microstructure and properties of thick X80 pipeline steel produced by hot continuous rolling","volume":"30","author":"Zhu","year":"2009","journal-title":"Iron Steel Vanadium Titanium"},{"key":"S1431927613012348_ref001","first-page":"390","article-title":"Effects of aging on microstructure and mechanical property of ultralow carbon acicular ferrite steel","volume":"45","author":"Guo","year":"2009","journal-title":"Acta Metall Sin"},{"key":"S1431927613012348_ref004","doi-asserted-by":"publisher","DOI":"10.1016\/S1006-706X(08)60013-8"},{"key":"S1431927613012348_ref005","first-page":"48","article-title":"Interaction between dissolved vanadium atom and [100](001) dislocation in iron","volume":"17","author":"Shu","year":"2005","journal-title":"J Iron Steel Res"}],"container-title":["Microscopy and Microanalysis"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S1431927613012348","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,2,14]],"date-time":"2023-02-14T20:33:46Z","timestamp":1676406826000},"score":1,"resource":{"primary":{"URL":"https:\/\/academic.oup.com\/mam\/article\/19\/S5\/62\/6932374"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,8]]},"references-count":10,"journal-issue":{"issue":"S5","published-print":{"date-parts":[[2013,8]]}},"alternative-id":["S1431927613012348"],"URL":"https:\/\/doi.org\/10.1017\/s1431927613012348","relation":{},"ISSN":["1431-9276","1435-8115"],"issn-type":[{"value":"1431-9276","type":"print"},{"value":"1435-8115","type":"electronic"}],"subject":[],"published":{"date-parts":[[2013,8]]}}}
