Recently, however, more high strength and more high creep resistant materials are required in industry such as air space industry. The aim of this work is to develop a new high strength Al-base eutectic casting alloy made by commercial foundry technique. As an example, an Al-12.7 mass% Ce-5.5 mass% Ni-0.56 mass% Zr alloy was adopted for age hardening cast alloy, on which the age hardening behavior was studied and the hardening mechanism was discussed. The alloy showed clear age hardening behavior and the hardeness reached a peak value of 108.6 Hv for aging of 500 h at 573 K, which was about two times higher than that of as-cast state in the Al-12 mass% Ce-5 mass% Ni eutectic cast alloy. The hardening mechanism was presumed to be due to Al₃Zr precipitation in the Al matrix phase. Finally, the Al-12.7 mass%Ce-5.5 mass% Ni-0.56 mass% Zr alloy was concluded to be a good candidate for new Al-base structural materials.","subitem_description_type":"Other"}]},"item_10002_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"秋田大学工学資源学部"}]},"item_10002_source_id_27":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13457241","subitem_source_identifier_type":"ISSN"}]},"item_10002_source_id_35":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA11410906","subitem_source_identifier_type":"NCID"}]},"item_10002_version_type_37":{"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":"小松, 芳成"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"後藤, 正治"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"麻生, 節夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Komatsu, Yoshinari","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Goto, Shoji","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Aso, Setsuo","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":"koushi28d.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"koushi28d.pdf","url":"https://air.repo.nii.ac.jp/record/725/files/koushi28d.pdf"},"version_id":"e759d84f-364f-4549-a75e-28c0f0671d05"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"高強度アルミニウム","subitem_subject_scheme":"Other"},{"subitem_subject":"鋳造合金","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":"高強度アルミニウム共晶系鋳造合金の開発","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"高強度アルミニウム共晶系鋳造合金の開発"}]},"item_type_id":"10002","owner":"3","path":["641"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-01-29"},"publish_date":"2008-01-29","publish_status":"0","recid":"725","relation_version_is_last":true,"title":["高強度アルミニウム共晶系鋳造合金の開発"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-25T11:17:31.137962+00:00"}
