Two types of pellets were used: one reduced with CO, and one reduced with H<sub>2</sub>. Prismatic-shaped specimens were fractured in a brittle manner during the compression tests at 300 K and 973 K. The fracture stress at 300 K of the specimen reduced with CO is nearly the same as that reduced with H<sub>2</sub> while the fracture stress at 973 K of the specimen reduced with CO is higher than that with H<sub>2</sub>. They show plastic deformation at higher than 1173 K. The yield stress of both types of specimens is nearly the same at above 1173 K. Poisson’s ratio varied during deformation, suggesting deformation mechanism changes as deformation proceeded. The strain distribution of a specimen deformed at 1273 K measured using digital image correlation showed plastic deformation accumulated near the pores. It is considered that not only the collapse of the pores but also the plastic deformability of the matrix itself influences the temperature dependence of the yield stress of pellets.</p>"}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1410026271643417218","@type":"Researcher","personIdentifier":[{"@type":"ORCID","@value":"0000-0002-4982-257X"},{"@type":"NRID","@value":"9000415346813"}],"foaf:name":[{"@language":"en","@value":"Tanaka Masaki"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Department of Materials, Faculty of Engineering, Kyushu University"}]},{"@id":"https://cir.nii.ac.jp/crid/1410026271643417219","@type":"Researcher","personIdentifier":[{"@type":"ORCID","@value":"0000-0003-0360-1859"}],"foaf:name":[{"@language":"en","@value":"Yamasaki Shigeto"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Department of Materials, Faculty of Engineering, Kyushu University"}]},{"@id":"https://cir.nii.ac.jp/crid/1420845751145934080","@type":"Researcher","personIdentifier":[{"@type":"KAKEN_RESEARCHERS","@value":"00274506"},{"@type":"NRID","@value":"1000000274506"},{"@type":"ORCID","@value":"0000-0002-2978-7623"},{"@type":"NRID","@value":"9000002965802"},{"@type":"NRID","@value":"9000392808357"},{"@type":"NRID","@value":"9000399361233"},{"@type":"NRID","@value":"9000409896084"},{"@type":"NRID","@value":"9000410757418"},{"@type":"NRID","@value":"9000345327923"},{"@type":"NRID","@value":"9000257851081"},{"@type":"NRID","@value":"9000411522557"},{"@type":"NRID","@value":"9000259332790"},{"@type":"NRID","@value":"9000363211967"},{"@type":"NRID","@value":"9000403990509"},{"@type":"NRID","@value":"9000017328862"}],"foaf:name":[{"@language":"en","@value":"Morikawa Tatsuya"}],"jpcoar:affiliationName":[{"@language":"en","@value":"Department of Materials, Faculty of Engineering, Kyushu University"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"09151559"},{"@type":"EISSN","@value":"13475460"}],"prism:publicationName":[{"@language":"en","@value":"ISIJ International"},{"@language":"ja","@value":"ＩＳＩＪ　Ｉｎｔｅｒｎａｔｉｏｎａｌ"},{"@language":"en","@value":"ISIJ Int."},{"@language":"en","@value":"ISIJ International"},{"@language":"ja","@value":"ＩＳＩＪ　Ｉｎｔｅｒｎａｔｉｏｎａｌ"}],"dc:publisher":[{"@language":"en","@value":"The Iron and Steel Institute of Japan"},{"@language":"ja","@value":"一般社団法人 日本鉄鋼協会"}],"prism:publicationDate":"2025-05-30","prism:volume":"65","prism:number":"6","prism:startingPage":"778","prism:endingPage":"782"},"reviewed":"false","url":[{"@id":"https://www.jstage.jst.go.jp/article/isijinternational/65/6/65_ISIJINT-2025-017/_pdf"}],"availableAt":"2025-05-30","foaf:topic":[{"@id":"https://cir.nii.ac.jp/all?q=plastic%20deformation","dc:title":"plastic deformation"},{"@id":"https://cir.nii.ac.jp/all?q=pellets","dc:title":"pellets"},{"@id":"https://cir.nii.ac.jp/all?q=blast%20furnace","dc:title":"blast furnace"},{"@id":"https://cir.nii.ac.jp/all?q=hydrogen","dc:title":"hydrogen"},{"@id":"https://cir.nii.ac.jp/all?q=pore","dc:title":"pore"},{"@id":"https://cir.nii.ac.jp/all?q=high%20temperature","dc:title":"high temperature"}],"relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360294645688797056","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"Hydrogen direct reduction (H-DR) in steel industry—An overview of challenges and opportunities"}]},{"@id":"https://cir.nii.ac.jp/crid/1360300157763957376","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"Green steel at its crossroads: Hybrid hydrogen-based reduction of iron ores"}]},{"@id":"https://cir.nii.ac.jp/crid/1360301472218048000","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"Acquisition of microscopic and local stress-strain curves by combination of HR-EBSD and DIC methods"}]},{"@id":"https://cir.nii.ac.jp/crid/1360579819756768896","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"Hydrogen Ironmaking: How It Works"}]},{"@id":"https://cir.nii.ac.jp/crid/1360586670921911424","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"Hydrogen reduction of iron ore pellets: A surface study using ambient pressure X-ray photoelectron spectroscopy"}]},{"@id":"https://cir.nii.ac.jp/crid/1360865424765193728","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"Effect of FeO concentration in sinter iron ore on reduction behavior in a hydrogen-enriched blast furnace"}]},{"@id":"https://cir.nii.ac.jp/crid/1361418520403715328","@type":"Article","relationType":["references"],"jpcoar:relatedTitle":[{"@value":"Gaseous reduction of iron oxides: Part I.
