Fine equiaxed α grains randomly oriented with [0001] perpendicular to tensile axis were produced in the CS. No significant difference of 10^7 cycles fatigue strength was recognized among the test materials at each temperature, although the CS exhibited an improved fatigue strength in long-life regime at 293 K. The subsurface crack initiation was dominant in lower stress level and at 77 K. The subsurface crack initiation sites consisted of facet or facets. The facets were identified as (0001) in the L, T and CR. In the CS, the (0001) facet provided an origin of subsurface crack initiation site, but the {1010} facets mainly covered the sites at 77 K. The combination of shear stress and opening stress on {1010} may be responsible for forming a facet and its growth in the neighboring grain. The dependence of subsurface crack initiation site size on the maximum stress range was evaluated, where the maximum stress intensity factor range, ΔK_(Imax), revealed the temperature and stress dependences.","subitem_description_type":"Abstract"}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"一般社団法人日本鉄鋼協会"}]},"item_2_relation_13":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.2355/isijinternational.ISIJINT-2017-673","subitem_relation_type_select":"DOI"}}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA12106117","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"13475460","subitem_source_identifier_type":"ISSN"}]},"item_2_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Faculty of Engineering, Yokohama National University"},{"subitem_text_value":"Graduate School of Engineering, Yokohama National University"},{"subitem_text_value":"Graduate School of Engineering, Yokohama National University"}]},"item_2_version_type_18":{"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":"Umezawa, Osamu"}],"nameIdentifiers":[{"nameIdentifier":"480","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"20343171","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=20343171"}]},{"creatorNames":[{"creatorName":"Yuasa, Takayuki"}],"nameIdentifiers":[{"nameIdentifier":"36744","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Li, Weibo"}],"nameIdentifiers":[{"nameIdentifier":"36745","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":"2020-03-09"}],"displaytype":"detail","filename":"ISIJ58_7.pdf","filesize":[{"value":"5.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ISIJ58_7.pdf","url":"https://ynu.repo.nii.ac.jp/record/10368/files/ISIJ58_7.pdf"},"version_id":"67ca03a6-b357-4ab9-9885-6506a9b52385"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"texture, macrozone","subitem_subject_scheme":"Other"},{"subitem_subject":"transgranular crack","subitem_subject_scheme":"Other"},{"subitem_subject":"titanium alloys","subitem_subject_scheme":"Other"},{"subitem_subject":"fatigue","subitem_subject_scheme":"Other"},{"subitem_subject":"subsurface crack initiation","subitem_subject_scheme":"Other"},{"subitem_subject":"low temperature","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":"Fractographical Analyses of Crack Initiation Site in High-cycle Fatigue for Ti–Fe–O Alloy at Low Temperature","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Fractographical Analyses of Crack Initiation Site in High-cycle Fatigue for Ti–Fe–O Alloy at Low Temperature"}]},"item_type_id":"2","owner":"3","path":["496"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-03-09"},"publish_date":"2020-03-09","publish_status":"0","recid":"10368","relation_version_is_last":true,"title":["Fractographical Analyses of Crack Initiation Site in High-cycle Fatigue for Ti–Fe–O Alloy at Low Temperature"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-06-20T18:30:45.839358+00:00"}
