The promotion effect was \n valuated by relative density, tensile strength,   Vickers hardness, electrical conductivity, and SEM microstructure observation. As a result, when the hot-press pressure was 40MPa and the sintering time was 10 minutes in the Ar inert gas atmosphere, great promotion was obtained at 800°C. For example, the relative density could be improved from 84.4% to 95.6% (at 20 kHz), and the tensile strength could be improved from 291MPa to 592MPa (at 20kHz). However, at a lower temperature at 600 and 700°C and a higher temperature of 900°C, the improvement range became smaller.","subitem_description_type":"Abstract"}]},"item_10002_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"2294","nameIdentifierScheme":"WEKO"}],"names":[{"name":"HORIGUCH, Katsumi"}]},{"nameIdentifiers":[{"nameIdentifier":"2295","nameIdentifierScheme":"WEKO"}],"names":[{"name":"MORIYAMA, Minoru"}]}]},"item_10002_heading_23":{"attribute_name":"見出し","attribute_value_mlt":[{"subitem_heading_banner_headline":"学術論文","subitem_heading_language":"ja"}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA1259397X","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1882-9155","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"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":"堀口, 勝三"}],"nameIdentifiers":[{"nameIdentifier":"2273","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"森山, 実"}],"nameIdentifiers":[{"nameIdentifier":"2274","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":"2022-06-30"}],"displaytype":"detail","filename":"56_1_05.pdf","filesize":[{"value":"849.9 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"56_1-05","url":"https://nagano-nct.repo.nii.ac.jp/record/1145/files/56_1_05.pdf"},"version_id":"a991c40e-8b1c-406a-b9e0-5c4a540ba897"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"超音波","subitem_subject_scheme":"Other"},{"subitem_subject":"ホットプレス焼結","subitem_subject_scheme":"Other"},{"subitem_subject":"Ti 粉末","subitem_subject_scheme":"Other"},{"subitem_subject":"高密度化","subitem_subject_scheme":"Other"},{"subitem_subject":"高強度化","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":"Ti粉末加圧焼結時の超音波付与による高密度化","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Ti粉末加圧焼結時の超音波付与による高密度化","subitem_title_language":"ja"}]},"item_type_id":"10002","owner":"17","path":["82"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2022-06-30"},"publish_date":"2022-06-30","publish_status":"0","recid":"1145","relation_version_is_last":true,"title":["Ti粉末加圧焼結時の超音波付与による高密度化"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-09-28T03:41:33.247560+00:00"}
