The experimental results have confirmed that by charging hydrogen into the steel, the Cr concentration decreases and the vacancy concentration increases in the inner layer oxide film. Additionally, the small punch test in the simulated BWR environment revealed that the stress corrosion cracking (SCC) was observed in the hydrogen charged steel and the oxidation of crack tip was accelerated. This result suggests that the initiation of SCC may be  strongly influenced by the HAO.","subitem_description_type":"Other"}]},"item_8_full_name_2":{"attribute_name":"著者よみ","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"コマザキ, シンイチ"}]}]},"item_8_full_name_3":{"attribute_name":"別言語の著者","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"KOMAZAKI, Shin-ichi"}]},{"nameIdentifiers":[{}],"names":[{"name":"駒崎, 慎一"}]}]},"item_8_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"鹿児島大学"}]},"item_8_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"531","subitem_subject_scheme":"NDC"},{"subitem_subject":"563","subitem_subject_scheme":"NDC"}]},"item_8_text_24":{"attribute_name":"公開者よみ","attribute_value_mlt":[{"subitem_text_value":"カゴシマ ダイガク"}]},"item_8_text_25":{"attribute_name":"公開者別名","attribute_value_mlt":[{"subitem_text_value":"Kagoshima University"}]},"item_8_text_41":{"attribute_name":"科研費番号 ","attribute_value_mlt":[{"subitem_text_value":"24656418"}]},"item_8_version_type_14":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"駒﨑, 慎一"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-10-27"}],"displaytype":"detail","filename":"24656418_駒崎慎一.pdf","filesize":[{"value":"2.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"24656418_駒崎慎一.pdf","url":"https://ir.kagoshima-u.ac.jp/record/1149/files/24656418_駒崎慎一.pdf"},"version_id":"5e8809de-9859-4aa4-b7f3-927c2962e59f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"低炭素オーステナイトステンレス鋼","subitem_subject_scheme":"Other"},{"subitem_subject":"酸化","subitem_subject_scheme":"Other"},{"subitem_subject":"水素","subitem_subject_scheme":"Other"},{"subitem_subject":"水素誘起加速酸化","subitem_subject_scheme":"Other"},{"subitem_subject":"高温高圧水中","subitem_subject_scheme":"Other"},{"subitem_subject":"酸化被膜","subitem_subject_scheme":"Other"},{"subitem_subject":"空孔濃度","subitem_subject_scheme":"Other"},{"subitem_subject":"スモールパンチ試験","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"高温高圧水中での水素連続チャージ技術の開発と水素有機加速酸化機構の解明","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"高温高圧水中での水素連続チャージ技術の開発と水素有機加速酸化機構の解明"}]},"item_type_id":"8","owner":"3","path":["79"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-05-21"},"publish_date":"2015-05-21","publish_status":"0","recid":"1149","relation_version_is_last":true,"title":["高温高圧水中での水素連続チャージ技術の開発と水素有機加速酸化機構の解明"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-12-25T07:15:29.950745+00:00"}
