In the experiment, the powder was molded at 98 MPa, and then sintering was performed at 1800-2250°C (150°C steps) with a constant sintering time of 60 minutes, and 30, 60, 120 and 180 minutes with a constant sintering temperature of 2100°C. \nThe properties of the sample sintered at 2100°C for 60 minutes are as follows. The relative density is 70.5%, Vickers hardness is 7.66 GPa, 4-point bending strength is 143MPa, fracture toughness (KIC) is 2.91 MPa･m1/2, Young's modulus is 356 GPa, Charpy impact strength is 19.1 kJ/m2, linear shrinkage is 7.56%, longitudinal wave speed of sound is 8.83km/s, transverse wave speed of sound is 5.33km/s, electrical conductivity is 1.51MS/m. TiN is a material that is difficult to sinter, but the pressureless sintering method is not subject to shape restrictions, so it is highly useful industrially.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"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","subitem_publisher_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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAlternatives":[{"creatorAlternative":"HORIGUCHI, Katsumi","creatorAlternativeLang":"en"}],"creatorNames":[{"creatorName":"堀口, 勝三","creatorNameLang":"ja"}]},{"creatorAlternatives":[{"creatorAlternative":"MORIYAMA, Minoru","creatorAlternativeLang":"en"}],"creatorNames":[{"creatorName":"森山, 実","creatorNameLang":"ja"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-06-30"}],"filename":"57_1-01.pdf","filesize":[{"value":"1 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"常圧焼結純TiNセラミックスの機械的及び電気的特性―焼結温度と焼結時間の影響―","url":"https://nagano-nct.repo.nii.ac.jp/record/2000001/files/57_1-01.pdf"},"version_id":"dc98685e-249b-4c5d-ab83-cf938de988fa"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"TiN","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"pressureless sintering","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"sintering temperature","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"mechanical property","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":"常圧焼結純TiNセラミックスの機械的及び電気的特性―焼結温度と焼結時間の影響―","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"常圧焼結純TiNセラミックスの機械的及び電気的特性―焼結温度と焼結時間の影響―","subitem_title_language":"ja"},{"subitem_title":"Mechanical and electrical properties of pure TiN ceramics by pressureless sintering －Effects of the sintering temperature and time－","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"17","path":["1693967363489"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-06-30"},"publish_date":"2023-06-30","publish_status":"0","recid":"2000001","relation_version_is_last":true,"title":["常圧焼結純TiNセラミックスの機械的及び電気的特性―焼結温度と焼結時間の影響―"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-09-28T05:37:08.775361+00:00"}
