When dynamic recrystallization occurred at 673 K, the stress\ndecreased. After the initial grain shape changed to dynamic recrystallization,\nthe stress-strain curves showed a steady state, and did not depend on the occurrence\nor the growth of voids. The peak strain, which is the strain at maximum\nstress, was hardly dependent on the size of the initial grain, but dependent on\nthe strain rate. Thus, the peak strain increases with strain rate. At this time,\nthe dynamic recrystallization form is a bulging mechanism and simultaneously,\na nucleation mechanism. This occurrence happened at about 20-30% peak\nstrain. Initial void formation depended on the strain rate. And the strain\nappearing void increased with increased in strain rate. Cavities of fractured\nspecimens showed 4 different shapes in three dimensions which corresponded to\ninitial grain size and strain rate. Fractured elongation reveals a tendency to\nbecome smaller, when cavities start to combine and grow into a45degree angle\nin relate to the tensile direction. On the other hand, the specimens exhibit large\nelongation, when cavi ties combine and grow in the tensile direction.","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本素材物性学会"}]},"item_10001_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN10140273","subitem_source_identifier_type":"NCID"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09199853","subitem_source_identifier_type":"ISSN"}]},"item_10001_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":"武藤, 侃"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"川岸, 秀一朗"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"田上, 道弘"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MUTO, Akira","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KAWAGISHI, Shuichiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TAGAMI, Michihiro","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-16"}],"displaytype":"detail","filename":"sozai12-8.pdf","filesize":[{"value":"2.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"sozai12-8.pdf","url":"https://air.repo.nii.ac.jp/record/1329/files/sozai12-8.pdf"},"version_id":"1e1423e3-f74d-495c-a3bb-bd0eaf71ca30"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"α-brass","subitem_subject_scheme":"Other"},{"subitem_subject":"high temperature deformation","subitem_subject_scheme":"Other"},{"subitem_subject":"grain size","subitem_subject_scheme":"Other"},{"subitem_subject":"strain rate","subitem_subject_scheme":"Other"},{"subitem_subject":"cavity","subitem_subject_scheme":"Other"},{"subitem_subject":"intermediate temperature em brittlement","subitem_subject_scheme":"Other"},{"subitem_subject":"high ductility","subitem_subject_scheme":"Other"},{"subitem_subject":"dynamic recrystallization","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"70-30黄銅の温度673Kにおける破断伸びと変形組織の関係","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"70-30黄銅の温度673Kにおける破断伸びと変形組織の関係"}]},"item_type_id":"10001","owner":"3","path":["825"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-10-29"},"publish_date":"2008-10-29","publish_status":"0","recid":"1329","relation_version_is_last":true,"title":["70-30黄銅の温度673Kにおける破断伸びと変形組織の関係"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-25T11:54:22.932636+00:00"}
