ECAP後の粒径と加熱後の組織安定性:純Al、Al-3%Mg合金、Al-0.2%Zr合金、Al-0.2%Sc合金、Al-3%Mg-0.2%Sc合金、Al-5.5%Mg-2.2%Li-0.12%Zr合金をECAPすることにより、それぞれ1.2、0.3、0.7、0.7、0.2、1.2μmの微細粒が得られた。純AlとAl-3%Mg合金では微細粒は473Kまで安定していた。Al-0.2%Zr合金では573Kまで、Al-0.2%Sc合金とAl-3%Mg-0.2%Sc合金では673Kまで微細粒が保たれた。ZrやScを含む合金が純AlやAl-Mg合金より高温まで微細粒の熱的安定性を保つ原因は、微細なL1_2規則粒子Al_3ZrとAl_3Scの存在によるものであり、Al_3ScはAl_3Zrよりもより高温までAl合金に対する再結晶抑制効果が顕著であることを示している。Al-5.5%Mg-2.2%Li-0.12%Zr合金では、微細粒は673Kまで安定に保たれた。 2. ホ-ル・ペッチの関係:Al-3%Mg合金では、結晶粒径0.2〜100μmの範囲でHv=46+35d^<-1/2>、Al-5.5%Mg-2.2%Li-0.12%Zr合金では、2〜60μmの範囲でHv=75+27d^<-1/2>(Hvはピッカ-ス硬度、dは結晶粒径)の関係が成り立った。 3. 超塑性特性:ECAPしたAl-3%Mg-0.2%Sc合金では673K、3.3x10^<-2>s^<-1>の条件で1030%、Al-5.5%Mg-2.2%Li-0.12%Zr合金では623K、10^<-2>s^<-1>の条件で1200%以上超塑性伸びを示した。破断部の結晶粒はつかみ部に比べて大きくなっており、応力誘起により粒成長が起こっていることがわかった。","subitem_description_type":"Abstract"}]},"item_18_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"平成9～10年度科学研究費補助金（基盤研究(C)(2)）研究成果報告書(課題番号09650764)","subitem_description_type":"Other"}]},"item_18_full_name_2":{"attribute_name":"著者（ヨミ）","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"1364","nameIdentifierScheme":"WEKO"}],"names":[{"name":"フルカワ, ミノル"}]}]},"item_18_publisher_18":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"福岡教育大学"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"古川, 稔"}],"nameIdentifiers":[{"nameIdentifier":"1363","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":"2020-09-28"}],"displaytype":"detail","filename":"Furukawa_kaken_9~10.pdf","filesize":[{"value":"24.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"Furukawa_kaken_9~10.pdf","url":"https://fukuoka-edu.repo.nii.ac.jp/record/464/files/Furukawa_kaken_9~10.pdf"},"version_id":"c016d05a-33f6-4b46-8609-3adb1e7ddf72"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ECAP method","subitem_subject_scheme":"Other"},{"subitem_subject":"ETYP:教育関連論文","subitem_subject_scheme":"Other"},{"subitem_subject":"ECAP法","subitem_subject_scheme":"Other"},{"subitem_subject":"Hall-Petch relationship","subitem_subject_scheme":"Other"},{"subitem_subject":"Hall-Petchの関係","subitem_subject_scheme":"Other"},{"subitem_subject":"Microstructural stability","subitem_subject_scheme":"Other"},{"subitem_subject":"Severe plastic strain","subitem_subject_scheme":"Other"},{"subitem_subject":"Superplasticity","subitem_subject_scheme":"Other"},{"subitem_subject":"Transmission electron microscope","subitem_subject_scheme":"Other"},{"subitem_subject":"Ultra fine grain","subitem_subject_scheme":"Other"},{"subitem_subject":"せん断変形","subitem_subject_scheme":"Other"},{"subitem_subject":"サブミクロン結晶粒","subitem_subject_scheme":"Other"},{"subitem_subject":"ホール・ペッチの関係","subitem_subject_scheme":"Other"},{"subitem_subject":"強ひずみ加工","subitem_subject_scheme":"Other"},{"subitem_subject":"強ひずみ加工法","subitem_subject_scheme":"Other"},{"subitem_subject":"組織安定性","subitem_subject_scheme":"Other"},{"subitem_subject":"超塑性特性","subitem_subject_scheme":"Other"},{"subitem_subject":"超微細結晶粒","subitem_subject_scheme":"Other"},{"subitem_subject":"電子顕微鏡観察","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"ECAP法で作製した超微細粒合金の組織安定性とホール・ぺッチの関係","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ECAP法で作製した超微細粒合金の組織安定性とホール・ぺッチの関係"}]},"item_type_id":"18","owner":"2","path":["70"],"pubdate":{"attribute_name":"公開日","attribute_value":"2010-06-01"},"publish_date":"2010-06-01","publish_status":"0","recid":"464","relation_version_is_last":true,"title":["ECAP法で作製した超微細粒合金の組織安定性とホール・ぺッチの関係"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-06-19T12:48:08.576475+00:00"}
