The sintering temperature was constant at 1950 ° C, and the sintering time was 3.6 ks. When the press pressure was increased, the densification occurred rapidly and the relative density reached 99.3% even at a low HP pressure of about 23.4 MPa. Furthermore, when the press pressure was 31.2 MPa, a relative density of 99.9%, a flexural strength of 502 MPa, and a hardness of 38.5 GPa were obtained. By using the HP method, B4C is able to obtain high properties and a smooth surface (mirror surface) by the HP sintering without adding a sintering aid.","subitem_description_type":"Abstract"}]},"item_10002_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"2281","nameIdentifierScheme":"WEKO"}],"names":[{"name":"HORIGUCHI, Katsumi"}]},{"nameIdentifiers":[{"nameIdentifier":"2282","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_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長野工業高等専門学校"}]},"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":"2279","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"森山, 実"}],"nameIdentifiers":[{"nameIdentifier":"2280","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_07.pdf","filesize":[{"value":"928.9 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"56_1-07","url":"https://nagano-nct.repo.nii.ac.jp/record/1147/files/56_1_07.pdf"},"version_id":"7a4d74c7-009f-4d8b-bbcf-52219b1ed60d"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"B₄C","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Hot press","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Density","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Strength","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Electric conductivity","subitem_subject_language":"en","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":"純B₄Cセラミックスホットプレス焼結体の機械的・電気的特性‐ホットプレス圧と雰囲気圧の影響‐","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"純B₄Cセラミックスホットプレス焼結体の機械的・電気的特性‐ホットプレス圧と雰囲気圧の影響‐","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":"1147","relation_version_is_last":true,"title":["純B₄Cセラミックスホットプレス焼結体の機械的・電気的特性‐ホットプレス圧と雰囲気圧の影響‐"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-09-28T03:45:00.146352+00:00"}
