Effect of microstructure of the material on the crack initiation and growth behavior was also studied using an atomic force microscope, AFM. Small crack with a length of 1-2μm initiates at grain boundary in the very early stage of fatigue life, N/N_f=6-10%. So the fatigue life is almost considered as a crack propagation life. The initiated crack propagated very slowly along the grain boundary especially at the lower stress amplitude region. The S-N curve can be estimated from an integration of the relation da/dN vs. M, the parameter proposed by authors.","subitem_description_type":"Abstract"}]},"item_2_description_40":{"attribute_name":"資源タイプ(DSpace)","attribute_value_mlt":[{"subitem_description":"Article","subitem_description_type":"Other"}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"10173","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"9000002438640","nameIdentifierScheme":"CiNii ID","nameIdentifierURI":"http://ci.nii.ac.jp/nrid/9000002438640"},{"nameIdentifier":"60019221","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://nrid.nii.ac.jp/nrid/1000060019221"}],"names":[{"name":"Ishihara, Sotomi"}]},{"nameIdentifiers":[{"nameIdentifier":"10358","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Saka, Shinji"}]},{"nameIdentifiers":[{"nameIdentifier":"10210","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"9000003801016","nameIdentifierScheme":"CiNii ID","nameIdentifierURI":"http://ci.nii.ac.jp/nrid/9000003801016"},{"nameIdentifier":"40170899","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://nrid.nii.ac.jp/nrid/1000040170899"}],"names":[{"name":"Shibata, Hiroshi"}]},{"nameIdentifiers":[{"nameIdentifier":"10174","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000080109107","nameIdentifierScheme":"CiNii ID","nameIdentifierURI":"http://ci.nii.ac.jp/nrid/1000080109107"},{"nameIdentifier":"80109107","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://nrid.nii.ac.jp/nrid/1000080109107"}],"names":[{"name":"Goshima, Takahito"}]}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"社団法人日本機械学会"}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"rights: 本文データは社団法人日本機械学会の許諾に基づきCiNiiから複製したものである"}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN0018742X","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03875008","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_16":{"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":"石原, 外美"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"坂, 晋二"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"柴田, 博司"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"五嶋, 孝仁"}],"nameIdentifiers":[{},{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-16"}],"displaytype":"detail","filename":"機械論文A05-479.pdf","filesize":[{"value":"971.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"機械論文A05-479.pdf","url":"https://toyama.repo.nii.ac.jp/record/3109/files/機械論文A05-479.pdf"},"version_id":"9d206caa-04c9-428f-8229-970d4d40645e"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Fatigue","subitem_subject_scheme":"Other"},{"subitem_subject":"Crack Propagation","subitem_subject_scheme":"Other"},{"subitem_subject":"Life Prediction","subitem_subject_scheme":"Other"},{"subitem_subject":"Crack Initiation","subitem_subject_scheme":"Other"},{"subitem_subject":"Microstructure","subitem_subject_scheme":"Other"},{"subitem_subject":"AFM","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":"原子間力顕微鏡によるアルミニウム合金押出材2024-T3の疲労き裂発生と進展挙動の観察","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"原子間力顕微鏡によるアルミニウム合金押出材2024-T3の疲労き裂発生と進展挙動の観察"}]},"item_type_id":"2","owner":"3","path":["558"],"pubdate":{"attribute_name":"公開日","attribute_value":"2007-12-20"},"publish_date":"2007-12-20","publish_status":"0","recid":"3109","relation_version_is_last":true,"title":["原子間力顕微鏡によるアルミニウム合金押出材2024-T3の疲労き裂発生と進展挙動の観察"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-25T11:51:45.558990+00:00"}
