An as-cold-rolled sheet steel with the chemical composition of (0.1-0.3) C-1.5Si-1.5Mn (mass%) was used in this study. For comparison, 0.14C-0.22Si-1.78Mn (mass%) DP steel was also prepared. The quenched DP steel is called MDPO, and the tempered DP steel is called MDP4. For butt welding, the blank obtained after the heat treatment was cut using a fine cutte, and YAG laser processing equipment was used. The press formability was evaluated from the maximum stretch-height (H_<max>). Tensile tests and stretch forming tests have been conducted for laser butt welded joints obtained from the combination of the different steel. The H_<max> value of the DPO steel was not controlled at the strength level of the MDP steel, and was not different from the H_<max> value of the MDP4 steel. It is thought that this was assisted to TRIP of the TDP steel because the tensile strength of the TDP steel is consequentially lower than that of the MDPO steel. High ductility and the high stretch-formability were able to be secured by the high strength tailored blank.","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":"三尾, 敦"},{"creatorName":"和田, 一秀"},{"creatorName":"大藪, 安澄"}],"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":"KJ00000136631.pdf","filesize":[{"value":"1.0 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"KJ00000136631.pdf","url":"https://nagano-nct.repo.nii.ac.jp/record/73/files/KJ00000136631.pdf"},"version_id":"8c50db4e-87f8-4c6d-99b1-6827343b43f2"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"YAGレーザ溶接","subitem_subject_scheme":"Other"},{"subitem_subject":"残留オーステナイト","subitem_subject_scheme":"Other"},{"subitem_subject":"TRIP鋼","subitem_subject_scheme":"Other"},{"subitem_subject":"テーラードブランク","subitem_subject_scheme":"Other"},{"subitem_subject":"プレス整形性","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":"YAGレーザ溶接したTRIP/DPテーラードブランクのプレス成形性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"YAGレーザ溶接したTRIP/DPテーラードブランクのプレス成形性"},{"subitem_title":"Press Formability of YAG Laser Welded TRIP/DP Tailored Blanks","subitem_title_language":"en"}]},"item_type_id":"2","owner":"7","path":["13"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-06-01"},"publish_date":"2012-06-01","publish_status":"0","recid":"73","relation_version_is_last":true,"title":["YAGレーザ溶接したTRIP/DPテーラードブランクのプレス成形性"],"weko_creator_id":"7","weko_shared_id":7},"updated":"2023-06-20T16:19:03.062462+00:00"}
