The specimens were tested in a bath filled with cooled alcohol or heated soya-bean oil, and the test temperature was regulated between -50℃ and 200℃. Under low temperature, the compressive strength σ_c of F and S is mainly governed by critical tensile stress σ_0, which is assumed to be equal to σ_0/1.5, and σ_b is the strength obtained from the bending tests. Under higher temperature, on the other hand, σ_c of these two products is governed by critical shearing stress τ_0. The fractured surfaces of these two products show brittle appearance under low temperature, but as temperature rises they tend to show ductile appearance. The wedge indentation strength σ_s, shows nearly equal tendency as σ_c, but the bending strength σ_b under higher temperature considerably differs from τ_0 in its temperature gradient. The critical tensile stress σ_0 and the critical shearing stress τ_0 are expressed as follows: σ_0=Ae^<S/T> τ_0=Be^<U/T> (S>U) where A, B, S, U are material constants and T is absolute temperature. Material E shows no temperature effect up to 200℃, and always shows brittle fracture.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA1511780000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学理工学研究所"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0371-6090","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162611","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学理工学研究所"},{"subitem_text_value":"東京大学理工学研究所"},{"subitem_text_value":"東京大学理工学研究所"}]},"item_9_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"THE INSTITUTE OF SCIENCE AND TECHNOLOGY UNIVERSITY OF TOKYO"},{"subitem_text_language":"en","subitem_text_value":"THE INSTITUTE OF SCIENCE AND TECHNOLOGY UNIVERSITY OF TOKYO"},{"subitem_text_language":"en","subitem_text_value":"THE INSTITUTE OF SCIENCE AND TECHNOLOGY UNIVERSITY OF TOKYO"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"吉識, 雅夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"竹鼻, 三雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"助川, 政之"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"YOSHIKI, Masao","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"TAKEHANA, Mitsuo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SUKEGAWA, Masayuki","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":"2020-01-24"}],"displaytype":"detail","filename":"SA1511780.pdf","filesize":[{"value":"2.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA1511780.pdf","url":"https://jaxa.repo.nii.ac.jp/record/34342/files/SA1511780.pdf"},"version_id":"fa1c6ee6-8441-4ab7-a681-76471e9b0cd7"}]},"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":"黒鉛製品の破壊に対する温度影響について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"黒鉛製品の破壊に対する温度影響について"}]},"item_type_id":"9","owner":"1","path":["1890","1908"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"34342","relation_version_is_last":true,"title":["黒鉛製品の破壊に対する温度影響について"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T23:44:02.125919+00:00"}
