The warm punching and successive warm expanding achieved the large stretch-flangeability, i.e., large hole-expanding ratio, low hole-expanding load and large hole-expanding height, by moderately suppressing the strain-induced transformation (SIT) of retained austenite particles. The hole-expanding ratio increased up to that of the ferrite-bainite dual-phase stee1. Optimum forming temperature Top for punching was　between 150 and 200℃, at which the SIT was suppressed the most. On the other hand, Top for expanding was between 50 and 200℃, and　linearly increased with increasing Ms of the retained austenite.","subitem_description_type":"Abstract"}]},"item_2_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長野工業高等専門学校"}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00179170","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0286-1909","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_20":{"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":"長坂, 明彦"}],"nameIdentifiers":[{"nameIdentifier":"852","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":"2013-02-19"}],"displaytype":"detail","filename":"nagano_nct-30-04.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"nagano_nct-30-04.pdf","url":"https://nagano-nct.repo.nii.ac.jp/record/371/files/nagano_nct-30-04.pdf"},"version_id":"a2316c71-39f0-464b-a8d2-ac432c9e37cc"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"0.2C-Si-1.5Mn複合組織鋼板の温間伸びフランジ性に及ぼす化学組成の影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"0.2C-Si-1.5Mn複合組織鋼板の温間伸びフランジ性に及ぼす化学組成の影響"}]},"item_type_id":"2","owner":"17","path":["35"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-02-19"},"publish_date":"2013-02-19","publish_status":"0","recid":"371","relation_version_is_last":true,"title":["0.2C-Si-1.5Mn複合組織鋼板の温間伸びフランジ性に及ぼす化学組成の影響"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-06-20T16:09:28.220307+00:00"}
