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"], "permalink_uri": "https://repo.qst.go.jp/records/82635", "pubdate": {"attribute_name": "公開日", "attribute_value": "2021-04-06"}, "publish_date": "2021-04-06", "publish_status": "0", "recid": "82635", "relation": {}, "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_shared_id": -1}
