The tensile strength (TS) of TBF steel austempered at 375℃ was higher than that of TBF steel austempered at 450℃. The press formability of laser cut surface layer was investigated by hole-expanding test. On the other hand, the stretch-flangeability (λ) of TBF steel in the case of hole-punching austempered at 375℃ was larger than that of TBF steel austempered at 450℃. Further, the stretch-flangeability austempered at 375℃ in the case of laser cutting at 4J/P was larger that that of 450℃. The strength-stretch-flangeability balance (TS×λ) of TBF steel austempered at 375℃ became maximum by laser cutting at 4J/P. The good stretch-flangeability was completed by laser cutting at 4J/P in TBF steel austempered at 375℃. The stretch-flangeability of laser cut hole depended on surface roughness in TBF steel austempered at 375℃. When a suitable condition of laser cutting is selected, the stretch-flangeability of laser cut hole is better than that of punched hole.","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"},{"creatorName":"窪田, 優一"},{"creatorName":"川尻, 將洋"},{"creatorName":"三尾, 敦"},{"creatorName":"北條, 智彦"},{"creatorName":"槙井, 浩一"}],"nameIdentifiers":[{"nameIdentifier":"0","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":"2012-06-01"}],"displaytype":"detail","filename":"KJ00004767866.pdf","filesize":[{"value":"822.8 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"KJ00004767866","url":"https://nagano-nct.repo.nii.ac.jp/record/168/files/KJ00004767866.pdf"},"version_id":"053eb2e5-02dc-4345-9a28-663d17369cf5"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"伸びフランジ性","subitem_subject_scheme":"Other"},{"subitem_subject":"残留オーステナイト","subitem_subject_scheme":"Other"},{"subitem_subject":"YAGレーザ切断","subitem_subject_scheme":"Other"},{"subitem_subject":"TRIP鋼","subitem_subject_scheme":"Other"},{"subitem_subject":"パルスエネルギー","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"TRIP型ベイニティックフェライト鋼板の伸びフランジ性に及ぼすYAGレーザ切断パルスエネルギーの影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"TRIP型ベイニティックフェライト鋼板の伸びフランジ性に及ぼすYAGレーザ切断パルスエネルギーの影響"},{"subitem_title":"Effect of YAG Laser Cutting Pulse Energy on Stretch flangeability of TRIP Steel Sheet with Bainitic Ferrite Matrix","subitem_title_language":"en"}]},"item_type_id":"2","owner":"7","path":["9"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-06-01"},"publish_date":"2012-06-01","publish_status":"0","recid":"168","relation_version_is_last":true,"title":["TRIP型ベイニティックフェライト鋼板の伸びフランジ性に及ぼすYAGレーザ切断パルスエネルギーの影響"],"weko_creator_id":"7","weko_shared_id":7},"updated":"2023-06-20T16:18:30.115878+00:00"}
