In order to examine capability of CTE design of ceramic matrix composites, CTEs of constituent materials (monolithic ceramics) were also examined. Temperature dependence and relative magnitude of CTEs for the monolithic ceramics were shown to be easily understood from the viewpoint of the relation of Grueneizen. Using the low of mixture based on the equivalent inclusion method, it was demonstrated that accurate design of CTE can be made, provided that temperature dependency and magnitude of CTE of SiC whisker is assumed to be smaller than that of the bulk SiC. This CTE behavior of SiC whisker was shown to be reasonable from the viewpoint of Grueneizen relation and Ruffa's theory, because the theory leads to low CTE and slow and gradual increase of CTE with temperature when elastic modulus and thus the Debye temperature are becomes higher.","subitem_description_type":"Other"}]},"item_7_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: DS0009405006","subitem_description_type":"Other"}]},"item_7_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0286-6013","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"八田, 博志"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"向後, 保雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"伊藤, 智紀"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"澤田, 豊"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hatta, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kogo, Yasuo","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ito, Tomonori","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sawada, Yutaka","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"セラミックス系複合材料","subitem_subject_scheme":"Other"},{"subitem_subject":"熱膨張係数","subitem_subject_scheme":"Other"},{"subitem_subject":"デバイ温度","subitem_subject_scheme":"Other"},{"subitem_subject":"グリュウナイゼンの関係","subitem_subject_scheme":"Other"},{"subitem_subject":"弾性率","subitem_subject_scheme":"Other"},{"subitem_subject":"比熱","subitem_subject_scheme":"Other"},{"subitem_subject":"等価介在物法","subitem_subject_scheme":"Other"},{"subitem_subject":"複合則","subitem_subject_scheme":"Other"},{"subitem_subject":"酸化ジルコニウム","subitem_subject_scheme":"Other"},{"subitem_subject":"アルミナ","subitem_subject_scheme":"Other"},{"subitem_subject":"ホイスカ","subitem_subject_scheme":"Other"},{"subitem_subject":"材料設計","subitem_subject_scheme":"Other"},{"subitem_subject":"温度依存性","subitem_subject_scheme":"Other"},{"subitem_subject":"マトリックス","subitem_subject_scheme":"Other"},{"subitem_subject":"数学モデル","subitem_subject_scheme":"Other"},{"subitem_subject":"ceramic matrix composites","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"coefficient of thermal expansion","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Debye temperature","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"relation of Grueneizen","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"elastic modulus","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"specific heat","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"equivalent inclusion method","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"mixing rule","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"zirconia","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"alumina","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"whisker","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"material design","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"temperature dependence","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"matrix","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"mathematical model","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"セラミックス系複合材料の高温熱膨張係数","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"セラミックス系複合材料の高温熱膨張係数"}]},"item_type_id":"7","owner":"1","path":["1888"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"21547","relation_version_is_last":true,"title":["セラミックス系複合材料の高温熱膨張係数"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:33:44.931198+00:00"}
