Pipes are manufactured from steels of a wide strength range. With the strength increase, a susceptibility to hydrogen embrittlement in general increases. This regularity is usually true for steels in the as-received state; however, the long-term operation can increase hydrogen susceptibility even of low- strength steels. This is caused by the development of damage dissipated in the metal bulk with the formation of voids due to deformation caused by high-pressure recombined hydrogen in them. Implementation of the hydrogen-induced damage mechanism, associated with the formation of deformation voids, extends the strength range of pipe steels, which become prone to operational hydrogen embrittlement.</p>","PeriodicalId":18230,"journal":{"name":"Materials Science","volume":"61 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2024-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140155578","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
