Identification of an optimum semi-solid condition for thixoforming is necessary not only for the construction of a system but also the fabrication of a near-net-shape product with fine microstructure. An online wavelet analysis system using Haar’s wavelet function, which is applied for its simplicity compared with Daubechies’ wavelet function, is developed to find the optimum operating condition. A thixoforming system, which is constructed adapting a threshold value as an index, monitors successfully a discontinuity of deformation of Al-Al3Ni FGM with the temperature rise. Thus, the timing of an operation is not at pre-fixed temperature but at the time when the index related to a wavelet function is satisfied. The concept is confirmed to be suitable from the micro-structural observation of the Al-Al3Ni FGM product, because the product under the optimum condition is found to have refined Al3Ni grains, which change from coarse grains and are expected to improve the mechanical properties.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_6_publisher_23":{"attribute_name":"公開者・出版者","attribute_value_mlt":[{"subitem_publisher":"Multidisciplinary Digital Publishing Institute","subitem_publisher_language":"en"}]},"item_6_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.3390/ma4122183","subitem_relation_type_select":"DOI"}}]},"item_6_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"19961944","subitem_source_identifier_type":"PISSN"}]},"item_6_subject_15":{"attribute_name":"NDC","attribute_value_mlt":[{"subitem_subject":"501","subitem_subject_scheme":"NDC"}]},"item_6_version_type_14":{"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":"Kumazawa, Noriyoshi","creatorNameLang":"en"},{"creatorName":"熊澤, 典良","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"122914","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Fukui, Yasuyoshi","creatorNameLang":"en"},{"creatorName":"福井, 泰好","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"122915","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nara, Daisaku","creatorNameLang":"en"},{"creatorName":"奈良, 大作","creatorNameLang":"ja"}],"nameIdentifiers":[{"nameIdentifier":"122916","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":"2016-10-28"}],"displaytype":"detail","filename":"materials-04-02183.pdf","filesize":[{"value":"469.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"materials-04-02183.pdf","objectType":"fulltext","url":"https://ir.kagoshima-u.ac.jp/record/6093/files/materials-04-02183.pdf"},"version_id":"10b6524e-7d94-4356-8e57-1d35cead23bb"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"wavelet analysis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"control","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"thixoforming","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"functionally graded material","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"intermetallic compound","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":"Novel Concept to Detect an Optimum Thixoforming Condition of Al-Al3Ni Functionally Graded Material by Wavelet Analysis for Online Operation","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Novel Concept to Detect an Optimum Thixoforming Condition of Al-Al3Ni Functionally Graded Material by Wavelet Analysis for Online Operation","subitem_title_language":"en"}]},"item_type_id":"6","owner":"18","path":["92"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2016-03-03"},"publish_date":"2016-03-03","publish_status":"0","recid":"6093","relation_version_is_last":true,"title":["Novel Concept to Detect an Optimum Thixoforming Condition of Al-Al3Ni Functionally Graded Material by Wavelet Analysis for Online Operation"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2024-02-07T07:13:15.646329+00:00"}
