In this study, Mn and Si-added Co-20Cr-15W-10Ni alloys (mass%,CCWN) were developed for the purpose of improving the performance of the CCWN alloy used for balloon-expandable stents.　The Mn-added CCWN alloys showed higher ductility as compared with the CCWN alloy, and showed a plastic deformation behavior in which the work-hardening rate increased during plastic deformation. Furthermore, it was suggested that the addition of Mn to the CCWN alloy is effective in reducing the yield stress of the alloy. The strength of the CCWN alloy was improved by adding Si. However, the addition of more than 1masss% of Si caused a decrease in ductility due to the formation of precipitates. From these results, it is considered that the addition of Mn to the CCWN alloy is one of the promising methods for developing high performance alloy for next-generation small-diameter stents.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目：研究活動スタート支援;  研究期間：2019～2020;   課題番号：19K23580;   研究分野：金属材料工学;   科研費の分科・細目：","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ(WEKO2)","attribute_value_mlt":[{"subitem_description":"Research Paper","subitem_description_type":"Other"}]},"item_8_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_8_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学"}]},"item_8_text_10":{"attribute_name":"著者 役割","attribute_value_mlt":[{"subitem_text_value":"研究代表者"}]},"item_8_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Ueki, Kosuke"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学理工学部; 助教"}]},"item_8_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Kindai University"}]},"item_8_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"植木, 洸輔"},{"creatorName":"ウエキ, コウスケ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"43369","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"10845928","nameIdentifierScheme":"NRID","nameIdentifierURI":"https://nrid.nii.ac.jp/ja/search/?kw=10845928"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-11-08"}],"displaytype":"detail","filename":"19K23580seika.pdf","filesize":[{"value":"400.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"19K23580seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/22143/files/19K23580seika.pdf"},"version_id":"efcf6af2-6d32-4c8c-9937-f1d6213d09c9"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"バルーン拡張型ステント","subitem_subject_scheme":"Other"},{"subitem_subject":"Co-Cr-W-Ni合金","subitem_subject_scheme":"Other"},{"subitem_subject":"機械的特性","subitem_subject_scheme":"Other"},{"subitem_subject":"微細組織制御","subitem_subject_scheme":"Other"},{"subitem_subject":"塑性変形挙動","subitem_subject_scheme":"Other"},{"subitem_subject":"析出挙動","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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"次世代小径ステント用TRIP/TWIP Co-Cr合金の開発","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"次世代小径ステント用TRIP/TWIP Co-Cr合金の開発","subitem_title_language":"ja"},{"subitem_title":"Development of TRIP/TWIP-assisted Co-Cr alloys for next generation small diameter stents","subitem_title_language":"en"}]},"item_type_id":"8","owner":"3","path":["4710"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2021-11-08"},"publish_date":"2021-11-08","publish_status":"0","recid":"22143","relation_version_is_last":true,"title":["次世代小径ステント用TRIP/TWIP Co-Cr合金の開発"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-08-13T06:46:02.770261+00:00"}
