The mixed powders with the compositions from TiB_2 to ZrB_2 (0.2mol step) were calcined at 1450℃ and then hotpressed at 2000℃ for 3.6ks under a pressing pressure of 32MPa in ambient Ar gas of normal pressure. As a result, the system had the solid solutions between TiB_2 and ZrB_2 crystal structures. The (TiB_2)_0.6(ZrB_2)_0.4 ceramics, for example, had the relative density of 96.5%, hardness of 33GPa, flexural strength of 354MPa, fracture toughness (K<IC>) of 3.87 MPa m<1/2> and Young's modulus of 449GPa. The ceramics is expected to use as ceramic mold materials that can form with electrical discharge machine, corrosion-resistant electrode materials, and electro-conductive hightemperature structural materials.","subitem_description_type":"Abstract"}]},"item_2_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長野工業高等専門学校"}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00179170","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0286-1909","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_20":{"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_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"森山, 実"}],"nameIdentifiers":[{"nameIdentifier":"767","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2013-02-19"}],"displaytype":"detail","filename":"nagano_nct-31-07.pdf","filesize":[{"value":"915.1 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"nagano_nct-31-07.pdf","url":"https://nagano-nct.repo.nii.ac.jp/record/342/files/nagano_nct-31-07.pdf"},"version_id":"7e23d686-fffc-46e7-acdd-899127c77b4a"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"固溶体","subitem_subject_scheme":"Other"},{"subitem_subject":"ホットプレス","subitem_subject_scheme":"Other"},{"subitem_subject":"機械的特性","subitem_subject_scheme":"Other"},{"subitem_subject":"TiB_2","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ZrB_2","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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"ホットプレス法によるTiB_2-ZrB_2系セラミックス焼結体の作製とその機械的特性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ホットプレス法によるTiB_2-ZrB_2系セラミックス焼結体の作製とその機械的特性"}]},"item_type_id":"2","owner":"17","path":["34"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-02-19"},"publish_date":"2013-02-19","publish_status":"0","recid":"342","relation_version_is_last":true,"title":["ホットプレス法によるTiB_2-ZrB_2系セラミックス焼結体の作製とその機械的特性"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-06-20T16:10:24.012290+00:00"}
