Elongation to\nfracture for fine-grained specimens shows high ductility and a maximum value in a range of\nintermediate temperature. The peak ductility increases with increasing in strain rate though it\ndoes not depend on the initial grain size. Type of the flow curves is controlled by the factors of\ntemperature, strain rate and initial grain size. The flow curve of coase-grained specimens shows\na serrated flow at lower temperatures and at higher strain rates while shows the work softening\nprocesses at other conditions. The flow curve of fine-grained specimens shows a typical flow\nbehavior of dynamic recrystallization. It should be noted that these flow curves tend to change\nfrom a type having simple peak due to dynamic recrystallization to another type having multiple\npeaks with decreasing initial grain size and strain rate and/or with increasing temperature.\nThe values of stress exponent and apparent activation energy for deformation range from 3 to\n5 and from 120 to 135kJ/mol, respectively. The main reason for this can be explained by a fact\nthat the both mechanisms of dislocation glide and grain boundary sliding occur simultaneously.","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":"後藤, 正治"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"加藤, 千秋"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"田上, 道弘"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MUTO, Akira","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"GOTO, Shoji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KATO, Chiaki","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":"sozai14-6.pdf","filesize":[{"value":"851.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"sozai14-6.pdf","url":"https://air.repo.nii.ac.jp/record/1309/files/sozai14-6.pdf"},"version_id":"5effd788-3248-499d-9a5c-1d5a0a5e485d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Cu-30mass%Zn","subitem_subject_scheme":"Other"},{"subitem_subject":"grain size","subitem_subject_scheme":"Other"},{"subitem_subject":"high temperature","subitem_subject_scheme":"Other"},{"subitem_subject":"stress exponent","subitem_subject_scheme":"Other"},{"subitem_subject":"activation energy","subitem_subject_scheme":"Other"},{"subitem_subject":"mechanical property","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":"Cu-30mass%Zn合金の高温延性に及ぼす結晶粒径とひずみ速度の影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Cu-30mass%Zn合金の高温延性に及ぼす結晶粒径とひずみ速度の影響"}]},"item_type_id":"10001","owner":"3","path":["821"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-10-27"},"publish_date":"2008-10-27","publish_status":"0","recid":"1309","relation_version_is_last":true,"title":["Cu-30mass%Zn合金の高温延性に及ぼす結晶粒径とひずみ速度の影響"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-25T11:54:49.959984+00:00"}
