Large-strained sheared edges are deformed and frequently cracked during stretch-flange formation. Considering shearing as the first deformation, the stretch-flange deformation may be regarded as a secondary deformation. To improve the stretch-flangeability of the DP steels, many researchers have analyzed the microvoid formation. However, in these analyses, the shearing process was not considered. With this background, ex-situ mini-bending tests combined with scanning electron microscopy (SEM) monitoring of microvoid formation were conducted during the secondary deformation. Prior to the secondary deformation, several microvoids were observed on the sheared surface and fine subgrains formed in the ferrite. During secondary deformation, the preliminary microvoids present at the ferrite-martensite interface propagated into the ferrite phase. In contrast, this behavior was not observed for the reamed surface deformation, which was formed without preliminary deformation. Furthermore, microvoids were initiated on ferrite grains that were not present at the ferrite-martensite interface, and martensite islands were not cracked during secondary deformation. This result is noteworthy because martensite cracking was the main factor involved in microvoid initiation, in the absence of shearing. Electron backscattering diffraction analysis revealed that the work hardening of ferrite, prior to the secondary deformation, caused a deviation in the strain concentration sites from those found in the reamed surface deformation. Therefore, this study elucidated microvoid formation on preliminary deformed surfaces via shearing and provided insights for material development considering deformations on the sheared surfaces of materials.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_30002_file35":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-06-30"}],"displaytype":"detail","fileDate":[{"fileDateType":"Issued","fileDateValue":"2023-06-30"}],"filename":"th109(6)_525.pdf","filesize":[{"value":"10.3 MB"}],"format":"application/pdf","licensetype":"license_5","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://repository.lib.tottori-u.ac.jp/record/2001650/files/th109(6)_525.pdf"},"version_id":"85498ec2-5baf-427c-96d1-b3c1371d0eda"}]},"item_30002_issue_number25":{"attribute_name":"号","attribute_value_mlt":[{"subitem_issue":"6"}]},"item_30002_language12":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_30002_number_of_pages26":{"attribute_name":"ページ数","attribute_value_mlt":[{"subitem_number_of_pages":"11"}]},"item_30002_page_end28":{"attribute_name":"終了ページ","attribute_value_mlt":[{"subitem_end_page":"535"}]},"item_30002_page_start27":{"attribute_name":"開始ページ","attribute_value_mlt":[{"subitem_start_page":"525"}]},"item_30002_publisher10":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"一般社団法人 日本鉄鋼協会","subitem_publisher_language":"ja"},{"subitem_publisher":"The Iron and Steel Institute of Japan ","subitem_publisher_language":"en"}]},"item_30002_relation18":{"attribute_name":"関連情報","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.2355/tetsutohagane.TETSU-2022-049","subitem_relation_type_select":"DOI"}}]},"item_30002_resource_type13":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_30002_rights6":{"attribute_name":"権利情報","attribute_value_mlt":[{"subitem_rights":"(C) 2023 The Iron and Steel Institute of Japan.
