Remelted zones with different thicknesses were formed on the surface of an AI-Cu-Si alloy casting plate, and backscattered waves were measured at various positions on the plate by immersion method with different distances of the water path to obtain an optimum focal depth in the specimen. When the ultrasonic wave was focused on the boundary between the remelted zone and the matrix, the amplitude ratio of the backscattered wave from the matrix to that from the remelted zone reached a maximum. The longitudinal wave velocity and the density were measured with test pieces containing remelted zones to obtain acoustic impedances of the remelted zone and the matrix. The\nreflectivity at the boundary calculated from the acoustic impedances was less than 1.5% (-37dB).","subitem_description_type":"Abstract"}]},"item_119_description_29":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"text","subitem_description_type":"Other"}]},"item_119_description_30":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_119_publisher_11":{"attribute_name":"出版者名","attribute_value_mlt":[{"subitem_publisher":"Elsevier Science Ltd."}]},"item_119_relation_16":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1016/S0963-8695(01)00047-0","subitem_relation_type_select":"DOI"}}]},"item_119_source_id_14":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"09638695","subitem_source_identifier_type":"ISSN"}]},"item_119_text_27":{"attribute_name":"版","attribute_value_mlt":[{"subitem_text_value":"[著者版]"}]},"item_119_text_3":{"attribute_name":"著者 ローマ字","attribute_value_mlt":[{"subitem_text_value":"Kato, Hiroshi"},{"subitem_text_value":"Jiang, Guoxin"},{"subitem_text_value":"Yoshida, Yuji"},{"subitem_text_value":"Komai, Tadahi"}]},"item_119_text_32":{"attribute_name":"アイテムID","attribute_value_mlt":[{"subitem_text_value":"A1001473"}]},"item_119_text_4":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"埼玉大学大学院理工学研究科人間支援・生産科学部門生産科学領域"}]},"item_119_text_5":{"attribute_name":"著者 所属(別言語)","attribute_value_mlt":[{"subitem_text_value":"Saitama University, Graduate School of Science and Engineering"}]},"item_119_text_9":{"attribute_name":"年月次","attribute_value_mlt":[{"subitem_text_value":"2002-6"}]},"item_119_textarea_25":{"attribute_name":"アクセス条件","attribute_value_mlt":[{"subitem_textarea_value":"Private"}]},"item_119_version_type_28":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"加藤, 寛"},{"creatorName":"カトウ, ヒロシ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-01-24"}],"displaytype":"detail","filename":"A1001473.pdf","filesize":[{"value":"412.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A1001473.pdf","url":"https://sucra.repo.nii.ac.jp/record/12605/files/A1001473.pdf"},"version_id":"7b42b6f2-3eda-4a2f-a60f-c68f171aad80"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"backscattered wave","subitem_subject_scheme":"Other"},{"subitem_subject":"aluminium alloy castings","subitem_subject_scheme":"Other"},{"subitem_subject":"remelted zone","subitem_subject_scheme":"Other"},{"subitem_subject":"acoustic impedance","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":"Optimization of ultrasonic measurement of remelted zone thickness using backscattered waves","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Optimization of ultrasonic measurement of remelted zone thickness using backscattered waves"}]},"item_type_id":"119","owner":"3","path":["426"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-03-26"},"publish_date":"2007-03-26","publish_status":"0","recid":"12605","relation_version_is_last":true,"title":["Optimization of ultrasonic measurement of remelted zone thickness using backscattered waves"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T12:58:29.968789+00:00"}
