The 9Cr-2WVTa steels were doped with 58Ni and 60Ni isotopes at 2 weight percent to control the rate of transmutation helium generation. The samples were irradiated in the High Flux Isotope Reactor to ~24 displacements per atom at nominal temperatures of 300, 400, and 500°C, producing 228 and 7 atomic parts-per-million helium in the 58Ni- and 60Ni-doped samples, respectively. Transmission electron microscopy revealed a variety of precipitates and the radiation-induced dislocation loops and cavities (voids or helium bubbles). Tensile tests of the irradiated samples at the irradiation temperatures showed radiation-induced hardening at 300°C and radiation-induced softening at 400°C. Analysis indicates that the hardening primarily originated from the loops and cavities. The 58Ni-doped samples had greater strengthening contributions from loops and cavities, leading to higher hardening with lower ductility than the 60Ni-doped samples. The greater helium production of 58Ni did not show pronounced reductions in ductility of the samples.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1016/j.jnucmat.2020.152634","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.sciencedirect.com/science/article/pii/S0022311520312423#!","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0022-3115","subitem_source_identifier_type":"ISSN"}]},"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":"Kim, B.K."}],"nameIdentifiers":[{"nameIdentifier":"1013256","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tan, L."}],"nameIdentifiers":[{"nameIdentifier":"1013257","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sakasegawa, H."}],"nameIdentifiers":[{"nameIdentifier":"1013258","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Parish, C.M."}],"nameIdentifiers":[{"nameIdentifier":"1013259","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Zhong, W."}],"nameIdentifiers":[{"nameIdentifier":"1013260","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hiroyasu, Tanigawa"}],"nameIdentifiers":[{"nameIdentifier":"1013261","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Katoh, Y."}],"nameIdentifiers":[{"nameIdentifier":"1013262","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hiroyasu, Tanigawa","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1013263","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":"Effects of helium on irradiation response of reduced-activation ferritic-martensitic steels: Using nickel isotopes to simulate fusion neutron response","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Effects of helium on irradiation response of reduced-activation ferritic-martensitic steels: Using nickel isotopes to simulate fusion neutron response"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-04-06"},"publish_date":"2021-04-06","publish_status":"0","recid":"82635","relation_version_is_last":true,"title":["Effects of helium on irradiation response of reduced-activation ferritic-martensitic steels: Using nickel isotopes to simulate fusion neutron response"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T18:53:15.174633+00:00"}
