As a result, it was found that the bolts heated at up to 673K did not show\na significant decrease in tightening force and Vickers hardness and the bolts heat-treated at the temperature higher\nthan 673K did. This is because the tempering temperature for the bolts after quenching in manufacturing process is\nclose to 673K. However, the bolts heated at 1073K and subsequently water-quenched showed a significant increase\nin Vickers hardness due to the formation of martensite phase by quenching from austenite phase. Moreover, the slip\nfactors of friction-type high strength bolted joints with pre-heated bolts were studied. As a result, it was found that\nthe slip factors almost kept constant when using the bolts heated at up to 673K, but the factors fell below 0.5 when\nusing the bolts heated at 773K and 873K.","subitem_description_type":"Abstract"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2434-3706","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"山浦 , 真一"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"矢野 , 友就"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"佐藤 , 樹"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"古屋 , 有務"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"奥屋 , 和彦"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yamaura, Shin-ichi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Furuya, Amu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Okuya, Kazuhiko","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-08-11"}],"displaytype":"detail","filename":"37-2-2 ronbunyamaura.pdf","filesize":[{"value":"2.9 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"【論文】鋼構造用高力ボルトの金属微細組織および機械的強度に対する熱履歴の影響","url":"https://ptu.repo.nii.ac.jp/record/107/files/37-2-2 ronbunyamaura.pdf"},"version_id":"3d6c80da-d461-4940-b474-71fdebc766d5"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Torshear-type high strength bolt","subitem_subject_scheme":"Other"},{"subitem_subject":"friction-type high strength bolted joint","subitem_subject_scheme":"Other"},{"subitem_subject":"slip factor","subitem_subject_scheme":"Other"},{"subitem_subject":"Vickers hardness","subitem_subject_scheme":"Other"},{"subitem_subject":"Torshear-type high strength bolt","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"friction-type high strength bolted joint","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"slip factor","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Vickers hardness","subitem_subject_language":"en","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":"【論文】鋼構造用高力ボルトの金属微細組織および機械的強度に対する熱履歴の影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"【論文】鋼構造用高力ボルトの金属微細組織および機械的強度に対する熱履歴の影響","subitem_title_language":"ja"}]},"item_type_id":"10001","owner":"6","path":["38"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2021-08-11"},"publish_date":"2021-08-11","publish_status":"0","recid":"107","relation_version_is_last":true,"title":["【論文】鋼構造用高力ボルトの金属微細組織および機械的強度に対する熱履歴の影響"],"weko_creator_id":"6","weko_shared_id":-1},"updated":"2023-06-22T01:43:11.725070+00:00"}
