In TRIP 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, mechanical punching or drilling decreased with increasing C content. When the C content was 0.3 mass% or higher, the hole-expanding ratio (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 mechanical punching. On the other hand, in TRIP steels of 0.3mass% C or higher the λ value of the hole obtained by laser cutting was low under high tensile strength (TS); however, the value was greatly improved by the post heat treatment. Based on the abore results, we demonstrated that the post heat treatment contributes to the improvement of the stretch-flangeability of (0.2-0.4)C-1.5Si-1.5Mn TRIP steels with polygonal ferrite matrix.","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":"新井, 剛"},{"creatorName":"小山, 敦史"},{"creatorName":"窪田, 優一"},{"creatorName":"田口, 信司"},{"creatorName":"掛川, 洋平"}],"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":"2012-05-31"}],"displaytype":"detail","filename":"KJ00004438491.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"url":"https://nagano-nct.repo.nii.ac.jp/record/147/files/KJ00004438491.pdf"},"version_id":"4d4973aa-8089-4b0c-bbe3-6c1cf33e3c0f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"YAGレーザ切断","subitem_subject_scheme":"Other"},{"subitem_subject":"後熱処理","subitem_subject_scheme":"Other"},{"subitem_subject":"伸びフランジ性","subitem_subject_scheme":"Other"},{"subitem_subject":"TRIP鋼","subitem_subject_scheme":"Other"},{"subitem_subject":"残留オーステナイト","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":"ポリゴナルフェライト母相を有するTRIP鋼板の伸びフランジ性に及ぼすYAGレーザ切断と後熱処理の影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ポリゴナルフェライト母相を有するTRIP鋼板の伸びフランジ性に及ぼすYAGレーザ切断と後熱処理の影響"},{"subitem_title":"Effects of YAG Laser Cutting and Post Heat Treatment on Stretch-flangeability of TRIP steels with Polygonal Ferrite Matrix","subitem_title_language":"en"}]},"item_type_id":"2","owner":"7","path":["10"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-05-31"},"publish_date":"2012-05-31","publish_status":"0","recid":"147","relation_version_is_last":true,"title":["ポリゴナルフェライト母相を有するTRIP鋼板の伸びフランジ性に及ぼすYAGレーザ切断と後熱処理の影響"],"weko_creator_id":"7","weko_shared_id":-1},"updated":"2023-06-20T16:19:05.183594+00:00"}
