The lowest value is obtained at a content of about 2% Ni and the highest one at 6-8% Ni where the α-phase in the steel attains 40-50% in volume ratio. To consider the reason of high resistance of duplex stainless steels, WOL test, constant load test and electrochemical tests have been conducted using 25 Cr-6 Ni (α+γ) steel as well as 28 Cr-4 Ni (α) and 21 Cr-9 Ni (γ) steel which are equivalent on composition respectively to α- and γ-phases of the duplex steel determined by EPMA analysis. The duplex steel has higher value of <i>K</i><sub>ISCC</sub> and lower rate of crack propagation than those of any steel consisted of single phase. The cracks of duplex steels have been observed to propagate across α-phase and to be retarded by γ-phase. Electrochemical coupling of the γ-steel with the γ-steel while holding at each proof load makes no significant effects on their times to failure. The high SCC threshold stress of duplex stainless steels could be attributed to a keying effect of the γ-phase which is caused by mechanical effects based on mixed (α+γ) duplex structure rather than an electrochemical one."}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1410282681237007232","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000365531371"},{"@type":"NRID","@value":"9000283131457"}],"foaf:name":[{"@language":"ja","@value":"長野 博夫"},{"@language":"en","@value":"Nagano Hiroo"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Central Research Laboratories, Sumitomo Meral Industries, Ltd."},{"@language":"ja","@value":"住友金属工業株式会社中央技術研究所"}]},{"@id":"https://cir.nii.ac.jp/crid/1410282681237007234","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000365531370"},{"@type":"NRID","@value":"9000283131456"}],"foaf:name":[{"@language":"ja","@value":"小若 正倫"},{"@language":"en","@value":"Kowaka Masamichi"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Central Research Laboratories, Sumitomo Meral Industries, Ltd."},{"@language":"ja","@value":"住友金属工業株式会社中央技術研究所"}]},{"@id":"https://cir.nii.ac.jp/crid/1410282681237007235","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000365531372"},{"@type":"NRID","@value":"9000283131458"}],"foaf:name":[{"@language":"ja","@value":"工藤 赳夫"},{"@language":"en","@value":"Kudo Takeo"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Central Research Laboratories, Sumitomo Meral Industries, Ltd."},{"@language":"ja","@value":"住友金属工業株式会社中央技術研究所"}]},{"@id":"https://cir.nii.ac.jp/crid/1410282681237007233","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000365531373"},{"@type":"NRID","@value":"9000283131459"}],"foaf:name":[{"@language":"ja","@value":"山中 和夫"},{"@language":"en","@value":"Yamanaka Kazuo"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Central Research Laboratories, Sumitomo Meral Industries, Ltd."},{"@language":"ja","@value":"住友金属工業株式会社中央技術研究所"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00109355"},{"@type":"EISSN","@value":"18841155"},{"@type":"NDL_BIB_ID","@value":"000000027399"},{"@type":"ISSN","@value":"00109355"},{"@type":"LISSN","@value":"00109355"},{"@type":"NCID","@value":"AN00225595"}],"prism:publicationName":[{"@language":"en","@value":"CORROSION ENGINEERING"},{"@value":"防食技術"}],"dc:publisher":[{"@language":"en","@value":"Japan Society of Corrosion Engineering"},{"@language":"ja","@value":"社団法人 腐食防食協会"}],"prism:publicationDate":"1981","prism:volume":"30","prism:number":"4","prism:startingPage":"218","prism:endingPage":"226"},"reviewed":"false","url":[{"@id":"http://id.ndl.go.jp/bib/2313219"},{"@id":"https://ndlsearch.ndl.go.jp/books/R000000004-I2313219"},{"@id":"https://www.jstage.jst.go.jp/article/jcorr1974/30/4/30_4_218/_pdf"},{"@id":"https://jlc.jst.go.jp/DN/JALC/00177088962?from=CiNii"}],"availableAt":"1981","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1361699993719123328","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"From War to Peace"}]}],"dataSourceIdentifier":[{"@type":"JALC","@value":"oai:japanlinkcenter.org:2002185771"},{"@type":"NDL_SEARCH","@value":"oai:ndlsearch.ndl.go.jp:R000000004-I2313219"},{"@type":"CROSSREF","@value":"10.3323/jcorr1974.30.4_218"},{"@type":"CIA","@value":"130006024608"},{"@type":"CIA","@value":"130004731422"}]}
