The measured strengths are so high that they are comparable to the theoretical strength of the intergranular glassy film (IGF). They are also widely scattered with a Weibull modulus of 3.0. The strength depends on the type of RE2O3 and increases in order of Y<La<Lu. It is suggested that the fracture occurs from the IGF/Si3N4 interfaces rather than within the IGF, and that O anions, which reside within the IGF and do not dissolve into the β-Si3N4 crystal lattice because of the high cationic field strength, reduce the IGF/grain interface strength. The GB strength also little depends on the misorientation angles, which is discussed in relation with the IGF accommodation ability of mismatch.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_2_relation_13":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/j.jeurceramsoc.2024.116672","subitem_relation_type_select":"DOI"}}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1873619X","subitem_source_identifier_type":"EISSN"}]},"item_2_version_type_18":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"Yokohama National University","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Matsuura, Komaki","creatorNameLang":"en"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"Yokohama National University","affiliationNameLang":"en"}]},{"affiliationNames":[{"affiliationName":"National Institute of Advanced Industrial Science and Technology (AIST)","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Ohji, Tatsuki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"0000-0002-4713-460X","nameIdentifierScheme":"ORCID","nameIdentifierURI":"https://orcid.org/0000-0002-4713-460X"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"Yokohama National University","affiliationNameLang":"en"}]},{"affiliationNames":[{"affiliationName":"Kanagawa Institute of Industrial Science and Technology","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Takahashi, Takuma","creatorNameLang":"en"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"Yokohama National University","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Iijima, Motoyuki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"0000-0003-1576-1403","nameIdentifierScheme":"ORCID","nameIdentifierURI":"https://orcid.org/0000-0003-1576-1403"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"Yokohama National University","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Tatami, Junichi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"0000-0002-4713-460X","nameIdentifierScheme":"ORCID","nameIdentifierURI":"https://orcid.org/0000-0002-4713-460X"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-07-24"}],"fileDate":[{"fileDateType":"Issued","fileDateValue":"2024-06-19"}],"filename":"1-s2.0-S0955221924005454-main.pdf","filesize":[{"value":"3.2 MB"}],"format":"application/pdf","licensetype":"license_5","mimetype":"application/pdf","url":{"url":"https://ynu.repo.nii.ac.jp/record/2001044/files/1-s2.0-S0955221924005454-main.pdf"},"version_id":"f80f9c2f-4b7b-4860-b735-8b0e528da800"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Silicon nitride, Grain boundary, Microscale, Fracture strength, Rare earth","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":"Effects of rare-earth oxides on grain boundary strength of silicon nitride ceramics","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Effects of rare-earth oxides on grain boundary strength of silicon nitride ceramics","subitem_title_language":"en"}]},"item_type_id":"2","owner":"17","path":["501"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-07-24"},"publish_date":"2024-07-24","publish_status":"0","recid":"2001044","relation_version_is_last":true,"title":["Effects of rare-earth oxides on grain boundary strength of silicon nitride ceramics"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2024-07-24T02:23:54.615441+00:00"}
