The addition of 0.15%Zr causes an increase in the strength and the resistance to stress relaxation of the alloy. The increase of strength or stress relaxation resistance is caused by the decrease in inter-precipitate spacing of Cr precipitates and the precipitation of Cu_5Zr phase or by the preferential formation of Cu_5Zr precipitates on dislocations in addition to Cr precipitates on dislocations. The addition of 0.1%Ag improves the strength, the bend formability and the resistance to stress relaxation. The increase in strength or stress relaxation resistance is attributable to the decrease in inter-precipitate, spacing of Cr precipitates and the suppression of recovery during aging or to the Ag-atom-drag effect on dislocation motion. The improvement of bend formability can be explained in terms of the increase in post-uniform elongation. The effect of equal-channel angular pressing (ECAP) and subsequent heat treatment on the mechanical properties of the Cu-Cr-Zr-Ag alloy has also been studied. The heat-treated ECAP alloy shows larger values of 0.2% proof stress, tensile stress and elongation to failure, but lower bend formability and stress relaxation resistance than the thermo-mechanically treated Cu-CrZr-Ag alloy.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:17560614, 研究期間(年度):2005-2006","subitem_description_type":"Other"},{"subitem_description":"出典：「ナノ組織制御によるCu-Cr-Ag-Zr系合金の電気的・機械的機能複合化」研究成果報告書　課題番号17560614\n  (KAKEN：科学研究費助成事業データベース（国立情報学研究所）)\n　　　本文データは著者版報告書より作成","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00052640","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_17":{"attribute_name":"公開者","attribute_value_mlt":[{"subitem_publisher":"金沢大学理工研究域機械工学系"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/search/?qm=20166466"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=20166466","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-17560614/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-17560614/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-17560614/175606142006kenkyu_seika_hokoku_gaiyo/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-17560614/175606142006kenkyu_seika_hokoku_gaiyo/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-11-01"}],"displaytype":"detail","filename":"TE-PR-MONZEN-R-kaken 2007-49p.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"TE-PR-MONZEN-R-kaken 2007-49p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/46307/files/TE-PR-MONZEN-R-kaken 2007-49p.pdf"},"version_id":"a1670e07-c44d-432c-84c2-b529f924fd2e"}]},"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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"ナノ組織制御によるCu-Cr-Ag-Zr系合金の電気的・機械的機能複合化","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ナノ組織制御によるCu-Cr-Ag-Zr系合金の電気的・機械的機能複合化"},{"subitem_title":"Composition of electrical and mechanical functions by controlling of nano-ltructure in Cu-Cr-Ag-Zr system alloys","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2827"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-11-01"},"publish_date":"2018-11-01","publish_status":"0","recid":"46307","relation_version_is_last":true,"title":["ナノ組織制御によるCu-Cr-Ag-Zr系合金の電気的・機械的機能複合化"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T14:34:01.097939+00:00"}
