The thermal history required for heat treatment was controlled with high accuracy. The welding residual stress around the yield stress could be relaxed by the heat treatment. The stress relaxation mechanism was elucidated by the thermal elastic plastic analysis considering the high temperature creep characteristics. The fatigue life in the low stress range (100MPa) of joints of which the residual stress was relaxed became twice as long as that of the joints as welded.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10_identifier_60":{"attribute_name":"URI","attribute_value_mlt":[{"subitem_identifier_type":"DOI","subitem_identifier_uri":"http://doi.org/10.2208/jscejseee.71.208"},{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/2237/25906"}]},"item_10_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"土木学会","subitem_publisher_language":"ja"}]},"item_10_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.2208/jscejseee.71.208","subitem_relation_type_select":"DOI"}}]},"item_10_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Copyright © 2015 公益社団法人 土木学会","subitem_rights_language":"en"}]},"item_10_select_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_10_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2185-4653","subitem_source_identifier_type":"EISSN"}]},"item_1615787544753":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"廣畑, 幹人","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"70375","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"伊藤, 義人","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"70376","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"HIROHATA, Mikihito","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"70377","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"ITOH, Yoshito","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"70378","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-02-22"}],"displaytype":"detail","filename":"1-7.pdf","filesize":[{"value":"1.9 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"1-7.pdf","objectType":"fulltext","url":"https://nagoya.repo.nii.ac.jp/record/23711/files/1-7.pdf"},"version_id":"f7d92420-88e0-4064-8181-c7eeb9e8b935"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"welding residual stress","subitem_subject_scheme":"Other"},{"subitem_subject":"post weld heat treatment","subitem_subject_scheme":"Other"},{"subitem_subject":"stress release annealing","subitem_subject_scheme":"Other"},{"subitem_subject":"fatigue strength","subitem_subject_scheme":"Other"},{"subitem_subject":"box welded joints","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"簡易熱源を用いた熱処理によるすみ肉まわし溶接継手の残留応力緩和に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"簡易熱源を用いた熱処理によるすみ肉まわし溶接継手の残留応力緩和に関する研究","subitem_title_language":"ja"}]},"item_type_id":"10","owner":"1","path":["322"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-04-07"},"publish_date":"2017-04-07","publish_status":"0","recid":"23711","relation_version_is_last":true,"title":["簡易熱源を用いた熱処理によるすみ肉まわし溶接継手の残留応力緩和に関する研究"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-01-16T04:13:39.931995+00:00"}
