High–speed tensile tests were conducted on high–Si ductile cast iron, conventional ferrite–pearlite ductile cast iron, and fully pearlitic ductile cast iron at a stroke speed ranging between 8.5 × 10−3–2.7 × 102 mm/s (strain rate of 2.1 × 10−4–1.8 × 101 s−1) and temperature ranging between −180°C–22°C. Then, σ B notch and σ B,RT smooth  were compared in terms of the strain rate–temperature parameter R = T ln (A/ ) to evaluate the combined influence of the strain rate   and temperature T. It was found that the notch strength σ B notch can be expressed as a unique master curve in terms of R parameter for each material. Then, a notch–strengthening threshold criterion R ≧ Rth was proposed to describe the lowest service temperature and highest strain rate that can be applied to the structural components. Under the condition R ≧ Rth, σ B notch  is always larger than σ B,RT smooth , and therefore, notched components can be used safely. In other words, if R ≧ Rth, σ B,RT smooth can be used to evaluate the notched components in machine design to prevent instantaneous fractures.","subitem_description_type":"Abstract"}]},"item_21_description_60":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"Journal Article","subitem_description_type":"Other"}]},"item_21_link_62":{"attribute_name":"研究者情報","attribute_value_mlt":[{"subitem_link_url":"https://hyokadb02.jimu.kyutech.ac.jp/html/10_ja.html"}]},"item_21_publisher_7":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Elsevier"}]},"item_21_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1016/j.engfracmech.2018.11.034","subitem_relation_type_select":"DOI"}}]},"item_21_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"Elsevier"}]},"item_21_select_59":{"attribute_name":"査読の有無","attribute_value_mlt":[{"subitem_select_item":"yes"}]},"item_21_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11526219","subitem_source_identifier_type":"NCID"}]},"item_21_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0013-7944","subitem_source_identifier_type":"ISSN"}]},"item_21_text_28":{"attribute_name":"論文ID（連携）","attribute_value_mlt":[{"subitem_text_value":"10334398"}]},"item_21_text_36":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"HINODE, Ltd., Azaiwasaki, Miyaki–cho, Miyaki–gun, Saga 849–0101, Japan"},{"subitem_text_value":"Kyushu Institute of Technology, Sensui–cho, Tobata–ku, Kitakyushu, Fukuoka 804–8550 Japan"},{"subitem_text_value":"Kyushu Institute of Technology, Sensui–cho, Tobata–ku, Kitakyushu, Fukuoka 804–8550 Japan"}]},"item_21_text_63":{"attribute_name":"連携ID","attribute_value_mlt":[{"subitem_text_value":"7549"}]},"item_21_version_type_58":{"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":"Ikeda,  Tomohiro"}],"nameIdentifiers":[{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"Noda, Nao-Aki","creatorNameLang":"en"},{"creatorName":"野田, 尚昭","creatorNameLang":"ja"},{"creatorName":"ノダ, ナオアキ","creatorNameLang":"ja-Kana"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{},{},{},{}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"Sano, Yoshikazu","creatorNameLang":"en"},{"creatorName":"佐野, 義一","creatorNameLang":"ja"},{"creatorName":"サノ, ヨシカズ","creatorNameLang":"ja-Kana"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-11-30"}],"displaytype":"detail","filename":"j.engfracmech.2018.11.034.pdf","filesize":[{"value":"1.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"j.engfracmech.2018.11.034.pdf","url":"https://kyutech.repo.nii.ac.jp/record/6772/files/j.engfracmech.2018.11.034.pdf"},"version_id":"db4602bf-0d83-4c66-8db0-18afd767d7e0"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Notch–strengthening threshold","subitem_subject_scheme":"Other"},{"subitem_subject":"Strain rate","subitem_subject_scheme":"Other"},{"subitem_subject":"Temperature","subitem_subject_scheme":"Other"},{"subitem_subject":"Ductile cast iron","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":"Conditions for notch strength to be higher than static tensile strength in high–strength ductile cast iron","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Conditions for notch strength to be higher than static tensile strength in high–strength ductile cast iron"}]},"item_type_id":"21","owner":"3","path":["24"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-11-30"},"publish_date":"2020-11-30","publish_status":"0","recid":"6772","relation_version_is_last":true,"title":["Conditions for notch strength to be higher than static tensile strength in high–strength ductile cast iron"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-10-25T07:42:27.663213+00:00"}
