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":"Other"}]},"item_20004_description_21":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_20004_full_name_16":{"attribute_name":"公開者(その他言語)","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"長野工業高等専門学校"}]}]},"item_20004_identifier_23":{"attribute_name":"資源識別子URI","attribute_value_mlt":[{"subitem_identifier_type":"URI","subitem_identifier_uri":"http://id.nii.ac.jp/1051/00000165/"}]},"item_20004_rights_50":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"CC BY-NC-ND"}]},"item_20004_source_id_25":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0286-1909","subitem_source_identifier_type":"ISSN"}]},"item_20004_source_id_26":{"attribute_name":"処理レコードID(総合目録DB)","attribute_value_mlt":[{"subitem_source_identifier":"AN00179170","subitem_source_identifier_type":"NCID"}]},"item_20004_version_type_51":{"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_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"url":{"url":"https://nagano-nct.repo.nii.ac.jp/?action=repository_action_common_download&item_id=168&item_no=1&attribute_id=22&file_no=1"}}]},"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"}]},"item_type_id":"20004","owner":"3","path":["351"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-04-01"},"publish_date":"2018-04-01","publish_status":"0","recid":"3442","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":"3","weko_shared_id":3},"updated":"2023-05-15T23:11:20.130110+00:00"}
