The Si-Hf alloy was utilized instead of pure Si for MI processing in order to lower the MI temperature to below 1400 C as well as to inhibit the thermal degradation of amorphous SiC fibers. Microstructural characterization revealed that the composite fabricated by Si-8.5 at%Hf alloy MI at 1375 C had a highly dense matrix comprising reaction-formed SiC and unreacted Si-HfSi2 phases. The Si-Hf alloy melt-infiltrated composite exhibited approximately 35% higher bending strength than a conventional Si melt-infiltrated composite fabricated at 1450 C. Further, it was confirmed that Si-Hf alloy melt-infiltrated composite maintained its strength up to 1200 C in an Ar atmosphere. These results clearly demonstrated that the Si-8.5 at%Hf alloy offers sufficient infiltration ability and reactivity to form a dense SiC-based matrix at 1375 C.","subitem_description_type":"Other"}]},"item_7_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: PA1520020000","subitem_description_type":"Other"}]},"item_7_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_7_relation_25":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"info:doi/10.1016/j.compositesa.2014.07.009"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://dx.doi.org/10.1016/j.compositesa.2014.07.009","subitem_relation_type_select":"DOI"}}]},"item_7_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1359-835X","subitem_source_identifier_type":"ISSN"}]},"item_7_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11069434","subitem_source_identifier_type":"NCID"}]},"item_7_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙航空研究開発機構航空本部(JAXA)"},{"subitem_text_value":"宇宙航空研究開発機構航空本部(JAXA)"},{"subitem_text_value":"東京工業大学原子炉工学研究所"},{"subitem_text_value":"東京工業大学原子炉工学研究所"},{"subitem_text_value":"東京工業大学原子炉工学研究所"}]},"item_7_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute of Aeronautical Technology, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Institute of Aeronautical Technology, Japan Aerospace Exploration Agency (JAXA)"},{"subitem_text_language":"en","subitem_text_value":"Research Laboratory for Nuclear Reactors, Tokyo Institute of Technology"},{"subitem_text_language":"en","subitem_text_value":"Research Laboratory for Nuclear Reactors, Tokyo Institute of Technology"},{"subitem_text_language":"en","subitem_text_value":"Research Laboratory for Nuclear Reactors, Tokyo Institute of Technology"}]},"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":"青木, 卓哉"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小笠原, 俊夫"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"大久保, 陽介"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"吉田, 克己"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"矢野, 豊彦"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Aoki, Takuya","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ogasawara, Toshio","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Okubo, Yosuke","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yoshida, Katsumi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Yano, Toyohiko","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Ceramic-matrix composites (CMCs)","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Mechanical properties","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Microstructures","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Liquid metal infiltration","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Fabrication and properties of Si-Hf alloy melt-infiltrated Tyranno ZMI fiber/SiC-based matrix composites","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Fabrication and properties of Si-Hf alloy melt-infiltrated Tyranno ZMI fiber/SiC-based matrix composites","subitem_title_language":"en"}]},"item_type_id":"7","owner":"1","path":["1888"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-07-07"},"publish_date":"2015-07-07","publish_status":"0","recid":"22607","relation_version_is_last":true,"title":["Fabrication and properties of Si-Hf alloy melt-infiltrated Tyranno ZMI fiber/SiC-based matrix composites"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T03:18:16.686820+00:00"}
