A remarkable area formed around the nonmetallic inclusion inside the fish-eye region on the fracture surface, which is a feature on the fracture surface in super long fatigue. This so-called GBF (granular-bright-facet) was observed in detail by a scanning probe microscope and a three-dimensional SEM. The GBF area, in which a rich carbide distribution was detected by EPMA, revealed a very rough and granular morphology in comparison with the area inside the fish-eye. It was clearly simulated by FRASTA that multiple microcracks were initiated and dispersed by the decohesion of a spherical carbide from the matrix around a nonmetallic inclusion, and converged into the GBF area during the fatigue process. After the formation of the GBF area, interior cracks grew radially and a fish-eye pattern formed on the fracture surface.","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":"10202","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"1000090019216","nameIdentifierScheme":"CiNii ID","nameIdentifierURI":"http://ci.nii.ac.jp/nrid/1000090019216"},{"nameIdentifier":"90019216","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://nrid.nii.ac.jp/nrid/1000090019216"}],"names":[{"name":"塩澤, 和章"}]}]},"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":"AA11179396","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1344-7912","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":"Shiozawa, Kazuaki"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"Morii, Yuuichi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Nishio, Seiichi"}],"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":"JSMEA06-01.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"JSMEA06-01.pdf","url":"https://toyama.repo.nii.ac.jp/record/3144/files/JSMEA06-01.pdf"},"version_id":"143329f9-c331-40b3-870f-d25d1bc1b592"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Long Life Fatigue","subitem_subject_scheme":"Other"},{"subitem_subject":"Subsurface Crack","subitem_subject_scheme":"Other"},{"subitem_subject":"Crack Initiation Mechanism","subitem_subject_scheme":"Other"},{"subitem_subject":"Fractography","subitem_subject_scheme":"Other"},{"subitem_subject":"Topographic Analysis","subitem_subject_scheme":"Other"},{"subitem_subject":"High Speed Tool Steel","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":"Subsurface Crack Initiation and Propagation Mechanism under the Super-Long Fatigue Regime for High Speed Tool Steel (JIS SKH51) by Fracture Surface Topographic Analysis (JSME Medal for Outstanding Paper in 2004)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Subsurface Crack Initiation and Propagation Mechanism under the Super-Long Fatigue Regime for High Speed Tool Steel (JIS SKH51) by Fracture Surface Topographic Analysis (JSME Medal for Outstanding Paper in 2004)"}]},"item_type_id":"2","owner":"3","path":["558"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-01-08"},"publish_date":"2008-01-08","publish_status":"0","recid":"3144","relation_version_is_last":true,"title":["Subsurface Crack Initiation and Propagation Mechanism under the Super-Long Fatigue Regime for High Speed Tool Steel (JIS SKH51) by Fracture Surface Topographic Analysis (JSME Medal for Outstanding Paper in 2004)"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-25T12:39:22.343840+00:00"}
