This study\nevaluated the mechanical properties and microstructure of a chemical vapor infiltrated SiC matrix composite,\nreinforced with a multi-layer SiC/pyrolytic carbon–coated Hi-NicalonTM Type S SiC fiber, following neutron\nirradiation at 319 and 629 °C to ∼100 displacements per atom. Both the proportional limit stress and ultimate\nflexural strength were significantly degraded as a result of irradiation at both temperatures. After irradiation at\n319 °C, the quasi-ductile fracture behavior of the nonirradiated composite became brittle, a result that was\nexplained by a loss of functionality of the fiber/matrix interface associated with the disappearance of the interphase\ndue to irradiation. The specimens irradiated at 629 °C showed increased apparent failure strain because\nthe fiber/matrix interphase was weakened by irradiation-induced partial debonding.","subitem_description_type":"Abstract"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.jeurceramsoc.2017.12.026","subitem_relation_type_select":"DOI"}}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Koyanagi, Takaaki"}],"nameIdentifiers":[{"nameIdentifier":"488193","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nozawa, Takashi"}],"nameIdentifiers":[{"nameIdentifier":"488194","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Katoh, Yutai"}],"nameIdentifiers":[{"nameIdentifier":"488195","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"L., Snead Lance"}],"nameIdentifiers":[{"nameIdentifier":"488196","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"野澤 貴史","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"488197","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Mechanical property degradation of high crystalline SiC fiber–reinforced SiC matrix composite neutron irradiated to ∼100 displacements per atom","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Mechanical property degradation of high crystalline SiC fiber–reinforced SiC matrix composite neutron irradiated to ∼100 displacements per atom"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-03-05"},"publish_date":"2018-03-05","publish_status":"0","recid":"48553","relation_version_is_last":true,"title":["Mechanical property degradation of high crystalline SiC fiber–reinforced SiC matrix composite neutron irradiated to ∼100 displacements per atom"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:26:52.017191+00:00"}
