The ceramic materials chosen for tensile tests were selected as representing existing and developing silicon nitride, silicon carbide and partially stabilized zirconia materials technology, suitable for gas turbine applications. The tensile strength of silicon nitride rapidly decreased at temperatures above 800～1000C. When the temperature increased to as high as 1300C, the strength decreased to about 10 percent of room temperature strength. On the other hand, the strength of silicon carbide did not change appreciably with temperatue. The strength of zirconia decreased with increasing temperatues. At 1000C the strength was reduced to 8 percent of room temperature strength. Observations of the fracture origin and of the crack propagation on the fracture surfaces were made and discussed.","subitem_description_type":"Other"}]},"item_3_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: NALTR0900000","subitem_description_type":"Other"}]},"item_3_description_33":{"attribute_name":"レポート番号","attribute_value_mlt":[{"subitem_description":"レポート番号: NAL TR-900","subitem_description_type":"Other"}]},"item_3_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"航空宇宙技術研究所"}]},"item_3_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"National Aerospace Laboratory(NAL)"}]},"item_3_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0389-4010","subitem_source_identifier_type":"ISSN"}]},"item_3_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"航空宇宙技術研究所原動機部"},{"subitem_text_value":"航空宇宙技術研究所原動機部"},{"subitem_text_value":"航空宇宙技術研究所航空機公害研究グループ"}]},"item_3_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Aeroengine Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Aeroengine Division, National Aerospace Laboratory(NAL)"},{"subitem_text_language":"en","subitem_text_value":"Noise and Emission Research Group, National Aerospace Laboratory(NAL)"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"藤沢, 良昭"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"松末, 勝利"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"高原, 北雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"FUJISAWA, Yoshiaki","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"MATSUSUE, Katsutoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TAKAHARA, Kitao","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-29"}],"displaytype":"detail","filename":"naltr00900.pdf","filesize":[{"value":"1.4 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"naltr00900.pdf","url":"https://jaxa.repo.nii.ac.jp/record/45159/files/naltr00900.pdf"},"version_id":"d8883ee8-9aac-4192-a1ca-36341fcd1829"}]},"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":"technical report","resourceuri":"http://purl.org/coar/resource_type/c_18gh"}]},"item_title":"構造用セラミックスの引張り強さ","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"構造用セラミックスの引張り強さ"}]},"item_type_id":"3","owner":"1","path":["1893","1917"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"45159","relation_version_is_last":true,"title":["構造用セラミックスの引張り強さ"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T21:44:17.087483+00:00"}
