The properties of currently employed ferritic/martensitic steels, particularly in terms of their creep resistance, fall short of meeting these stringent requirements. This study investigates how the creep resistance was improved for a HT9 steel by the oxide dispersion-strengthening (ODS) strategy. Experimental analyses demonstrate that HT9-ODS steel exhibits markedly superior creep resistance compared to that of conventional HT9 steel. Creep life predictions, based on the Monkman–Grant (M-G) relationship, reveal that under creep conditions of 650 °C and 120 MPa, the creep life of HT9-ODS can reach several hundred thousand hours, significantly higher than that of HT9, which is only in the range of tens of hours. Microstructural investigations indicate that the enhanced creep resistance of HT9-ODS is primarily due to the interaction between ultrafine, high-density nano oxide particles and dislocations during creep. The pinning and attraction of nano-oxide particles on dislocations leads to the generation of ‘threshold stress’. When the creep stress is lower than the threshold stress, creep deformation is difficult to proceed, therefore significantly extending the creep life. To further validate and predict the creep behavior of HT9-ODS, two dislocation creep models were applied, affirming the particle-strengthened dislocation creep mechanism as a key factor in its superior creep performance.</div></div>","PeriodicalId":18727,"journal":{"name":"Materials Characterization","volume":"223 ","pages":"Article 114939"},"PeriodicalIF":4.8,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143681151","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
