Casting defects were checked by X-ray transparencies and flow behavior was observed using the molten tracer element method. There was no difference between the two metals for F type fillings. However, for thin cavities(W type fillings)and mesh cavities(B type fillings), the castability of the titanium alloy was slightly lower than that of pure titanium. The thermal properties of the titanium alloy are presumed to be considerably different from those of pure titanium since platinum, one of the tracers, was hardly detected during mesh casting of the alloy. Microanalysis of the top of the mesh casting revealed that the molten alloy flow included many particles. In conclusion, the reason for the poorer castability of the titanium alloy is that the viscosity of the molten alloy increased significantly because of the solidification particles included in its flow.","subitem_description_type":"Abstract"}]},"item_5_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"39956","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Watanabe, Kouichi"}]},{"nameIdentifiers":[{"nameIdentifier":"39957","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Okawa, Seigo"}]},{"nameIdentifiers":[{"nameIdentifier":"39958","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kanatani, Mitsugu"}]},{"nameIdentifiers":[{"nameIdentifier":"39959","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Nakano, Syuji"}]},{"nameIdentifiers":[{"nameIdentifier":"39960","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Miyakawa, Osamu"}]},{"nameIdentifiers":[{"nameIdentifier":"39961","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Kobayashi, Masayoshi"}]}]},"item_5_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本歯科理工学会"}]},"item_5_relation_31":{"attribute_name":"異版である","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110002992708","subitem_relation_type_select":"URI"}}]},"item_5_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"日本歯科理工学会"},{"subitem_rights":"本文データは学協会の許諾に基づきCiNiiから複製したものである"}]},"item_5_select_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_select_item":"publisher"}]},"item_5_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00127279","subitem_source_identifier_type":"NCID"}]},"item_5_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"02865858","subitem_source_identifier_type":"ISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"渡辺, 孝一"}],"nameIdentifiers":[{"nameIdentifier":"39950","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"大川, 成剛"}],"nameIdentifiers":[{"nameIdentifier":"39951","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"金谷, 貢"}],"nameIdentifiers":[{"nameIdentifier":"39952","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"中野, 周二"}],"nameIdentifiers":[{"nameIdentifier":"39953","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"宮川, 修"}],"nameIdentifiers":[{"nameIdentifier":"39954","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小林, 正義"}],"nameIdentifiers":[{"nameIdentifier":"39955","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":"2019-07-30"}],"displaytype":"detail","filename":"110002992708.pdf","filesize":[{"value":"4.2 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"110002992708.pdf","url":"https://niigata-u.repo.nii.ac.jp/record/2933/files/110002992708.pdf"},"version_id":"4c788e93-baa0-4907-b3ac-ec16fc695495"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"チタン","subitem_subject_scheme":"Other"},{"subitem_subject":"チタン合金","subitem_subject_scheme":"Other"},{"subitem_subject":"湯流れ","subitem_subject_scheme":"Other"},{"subitem_subject":"鋳造性","subitem_subject_scheme":"Other"},{"subitem_subject":"Titanium","subitem_subject_scheme":"Other"},{"subitem_subject":"Titanium alloy","subitem_subject_scheme":"Other"},{"subitem_subject":"Flow of molten metal","subitem_subject_scheme":"Other"},{"subitem_subject":"Castability","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":"純チタンとTi-6Al-4V合金の湯流れの相違点","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"純チタンとTi-6Al-4V合金の湯流れの相違点"},{"subitem_title":"純チタンとTi-6Al-4V合金の湯流れの相違点","subitem_title_language":"en"}]},"item_type_id":"5","owner":"1","path":["454","476"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-04-05"},"publish_date":"2012-04-05","publish_status":"0","recid":"2933","relation_version_is_last":true,"title":["純チタンとTi-6Al-4V合金の湯流れの相違点"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-15T03:36:08.662774+00:00"}
