In this process named NIL/μ-SPiMIM, the feedstock composed of nano-sized copper powder and polyacetal-based binder was adequately prepared and molded into polymethylmethacrylate films with fine line-scan structures, and the molded parts were sintered in a reductive gas atmosphere followed by solvent debinding of the films. Thebehavior in debinding and sintering was investigated by thermo-gravimetric analysis, carbon and oxygen analysis and SEM observation. The effects of sintering temperature on sintered density and shrinkage, profile accuracy were evaluated systematically. It can be concluded that the manufacturing method named NIL/μ-SPiMIM proposed in this studyhas great potential to produce precisely 3 dimensional complex metallic parts with finemicro-structures.","subitem_description_type":"Abstract"}]},"item_8_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究種目：基盤研究(C);  研究期間：2008～2010;  課題番号：20560094;   研究分野：粉末成形加工;   科研費の分科・細目：工学・機械工学・機械材料・材料力学","subitem_description_type":"Other"}]},"item_8_description_37":{"attribute_name":"資源タイプ","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_relation_11":{"attribute_name":"著者 外部リンク","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/ja/r/30208235"}]}]},"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":"NISHIYABU, KAZUAKI"}]},"item_8_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学理工学部; 准教授"}]},"item_8_version_type_12":{"attribute_name":"版","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":"西籔,  和明"},{"creatorName":"ニシヤブ, カズアキ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-17"}],"displaytype":"detail","filename":"KAKEN_20560094seika.pdf","filesize":[{"value":"744.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KAKEN_20560094seika.pdf","url":"https://kindai.repo.nii.ac.jp/record/3136/files/KAKEN_20560094seika.pdf"},"version_id":"cdc00457-dc6b-44e9-91d9-2c659abaf56c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"粉末成形","subitem_subject_scheme":"Other"},{"subitem_subject":"金属粉末射出成形","subitem_subject_scheme":"Other"},{"subitem_subject":"焼結","subitem_subject_scheme":"Other"},{"subitem_subject":"マイクロ構造体","subitem_subject_scheme":"Other"},{"subitem_subject":"ナノ粒子","subitem_subject_scheme":"Other"},{"subitem_subject":"転写性","subitem_subject_scheme":"Other"},{"subitem_subject":"ナノインプリント","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":"ナノインプリント犠牲樹脂型インサート粉末射出成形によるマイクロ構造体の転写性評価","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ナノインプリント犠牲樹脂型インサート粉末射出成形によるマイクロ構造体の転写性評価"}]},"item_type_id":"8","owner":"3","path":["2693","2694"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-07-08"},"publish_date":"2011-07-08","publish_status":"0","recid":"3136","relation_version_is_last":true,"title":["ナノインプリント犠牲樹脂型インサート粉末射出成形によるマイクロ構造体の転写性評価"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-21T01:45:30.213757+00:00"}
