The simultaneous dual ion (nickel plus helium ions) irradiations were adopted to simulate nuclear irradiation environments such as fast reactor and fusion reactor at HIT to 1 or 10 dpa and to 0, 1, 10, and 100\nappm-He at 500, 550, and 600 °C. Thin foils for a transmission electron microscopy (TEM) were prepared with a focused ion beam (FIB) micro-sampling system. After the irradiation, the microstructures were observed by a transmission electron microscope and the irradiation hardening was measured by nano-indentation technique. In this study, the efficient of non-destructive measurement method of surface acoustic wave (SAW) excited by laser beam on the detection of radiation hardening behavior was also examined. Irradiation hardening was observed and the increment was tended to increase with dpa and He/dpa, which was especially effective in the condition of 100 appmHe/dpa even at 550 °C. Non-linear effect on amplitude of the excited SAW was also observed on the ion irradiated materials, and the propagation velocity of SAW was tended to be increased with irradiation dose. It was found that the behaviors of SAWs results were correlated with the changes of mechanical properties.","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.nme.2018.07.009","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/S2352179117301941","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2352-1791","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":"Wakai, E."}],"nameIdentifiers":[{"nameIdentifier":"794332","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"北澤, 真一"}],"nameIdentifiers":[{"nameIdentifier":"794333","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takaya, S."}],"nameIdentifiers":[{"nameIdentifier":"794334","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Okubo, N."}],"nameIdentifiers":[{"nameIdentifier":"794335","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nagae, Y."}],"nameIdentifiers":[{"nameIdentifier":"794336","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Iwai, T."}],"nameIdentifiers":[{"nameIdentifier":"794337","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Abe, H."}],"nameIdentifiers":[{"nameIdentifier":"794338","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Aoto, K."}],"nameIdentifiers":[{"nameIdentifier":"794339","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kitazawa, Shinichi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"794340","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 production, displacement damage on mechanical properties and surface acoustic wave in austenitic stainless steels and martensitic steel","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Effects of helium production, displacement damage on mechanical properties and surface acoustic wave in austenitic stainless steels and martensitic steel"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-01-31"},"publish_date":"2019-01-31","publish_status":"0","recid":"49527","relation_version_is_last":true,"title":["Effects of helium production, displacement damage on mechanical properties and surface acoustic wave in austenitic stainless steels and martensitic steel"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T23:56:28.037178+00:00"}
