In TDP steels in which Si and Mn contents were constant and C content was varied ((0.1-0.4)C - 1.5Si - 1.5Mn,mass%), the strength - stretch-flangeability balance (TS×λ) of holes obtained by either laser cutting, hole-punching or drilling decreased with increasing C content. When the C content was 0.3 mass% or higher, the λ value in the case of laser cutting, which originally was as good as that in the case of drilling, decreased to a level comparable to that in the case of hole-punching. On the other hand, in TDP steels in which Si and Mn contents were varied and C content was kept constant (0.2C-(1.0-2.0)Si - (1.0-2.0)Mn, mass%), the λ value of the hole obtained by hole-punching was low under high TS; however, the value was greatly improved by laser cutting. Based on the above results, we demonstrated that YAG laser cutting contributes to the improvement of the stretch-flangeability of 980-MPa-class TDP steels with 0.2 mass% C.","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":"NAGASAKA, Akihiko"}],"nameIdentifiers":[{"nameIdentifier":"340","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"MlO, Atsushi"}],"nameIdentifiers":[{"nameIdentifier":"341","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"WADA, Kazuhide"}],"nameIdentifiers":[{"nameIdentifier":"342","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-36-02.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"nagano_nct-36-02.pdf","url":"https://nagano-nct.repo.nii.ac.jp/record/202/files/nagano_nct-36-02.pdf"},"version_id":"32cda3e6-bd65-4744-b917-75bbfae12a73"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"YAG laser cutting","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"retained austenite","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"transformation-induced plasticity","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"stretch-flangeability","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Effect of YAG Laser Cutting on Stretch-flangeability of TRIP-aided Dual-phase Steel Sheets","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Effect of YAG Laser Cutting on Stretch-flangeability of TRIP-aided Dual-phase Steel Sheets","subitem_title_language":"en"}]},"item_type_id":"2","owner":"17","path":["14"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-02-19"},"publish_date":"2013-02-19","publish_status":"0","recid":"202","relation_version_is_last":true,"title":["Effect of YAG Laser Cutting on Stretch-flangeability of TRIP-aided Dual-phase Steel Sheets"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-06-20T16:14:31.810507+00:00"}
