Tensile stress is applied along <1120> direction. Plastic deformation, or nonlinearity, is observed in the stress–strain curves, and yield stress, or proportional limit, coincides between the two specimens at ≈25 ± 2 GPa. Scanning transmission electron microscopy and transmission electron microscopy studies show that the plastic deformation is due to dislocation activities; multiple-dislocation pileup areas are observed in both the specimens. Assuming {1100}/<1120> prismatic slip which most plausibly occurs in the <1120> stress application, the critical resolved shar stress is estimated to be 10.9 GPa, which agrees well with the previous studies. Measured fracture strength is 41.9 ± 2.8 and 33.5 ± 2.4 GPa for the A and B, respectively. Dislocation–fracture relationship is discussed on the basis of dislocation-based fracture mechanics, etc. It is suggested that cracks form within the multiple-dislocation pileup area, by interaction with dislocation pileups, and act as fracture origins. A's strength is close to an ideal tensile strength of 4H-SiC in the <1120> direction, 47–55 GPa.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Wiley","subitem_publisher_language":"en"}]},"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/10.1002/adem.202400095","subitem_relation_type_select":"DOI"}}]},"item_2_rights_14":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International","subitem_rights_language":"en","subitem_rights_resource":"https://creativecommons.org/licenses/by-nc-nd/4.0/"}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11558667","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"15272648","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"}]},{"affiliationNames":[{"affiliationName":"Kanagawa Institute of Industrial Science and Technology","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Yahagi, Tsukaho","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":"0000-0002-4880-9138","nameIdentifierScheme":"ORCID","nameIdentifierURI":"https://orcid.org/0000-0002-4880-9138"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"Yokohama National University","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Yamaguchi, Hiroshi","creatorNameLang":"en"}]},{"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"}],"nameIdentifiers":[{"nameIdentifier":"0009-0005-7568-3787","nameIdentifierScheme":"ORCID","nameIdentifierURI":"https://orcid.org/0009-0005-7568-3787"},{"nameIdentifier":"30715991","nameIdentifierScheme":"e-Rad_Researcher","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=30715991"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"Toyohashi University of Technology","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Nakano, Hiromi","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"00319500","nameIdentifierScheme":"e-Rad_Researcher","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=00319500"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"Yokohama National University","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Iijima, Motoyuki","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"70513745","nameIdentifierScheme":"e-Rad_Researcher","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=70513745"}]},{"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"},{"nameIdentifier":"30303085","nameIdentifierScheme":"e-Rad_Researcher","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=30303085"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-07-25"}],"displaytype":"detail","fileDate":[{"fileDateType":"Issued","fileDateValue":"2024-03-27"}],"filename":"Adv Eng Mater -
