The alloy contained two kinds of elongated α-phase microstructures, i.e., recovered α grains and recrystallized α grains. Untested samples contained mobile dislocations in recovered αgrains, but in recrystallized α grains, any dislocations were observed. Internal crack initiation sites were formed transgranularly and were related to the recrystallized α grain region, judging from their morphology, size, and chemistry. Dislocations in revovered α grains were rearranged after cyclic loading in either {0110}-<1120> planar arrays or subgrain structures due to dislocation annihilation. Few dislocations were seen in recrystallized α grains. We discuss the relationship between localized strain incompatibility due to coplanar arrays in recovered α grains and transgranular cracking in recrystallized α grains, and propose a model for fatigue crack generation.","subitem_description_type":"Abstract"}]},"item_2_full_name_2":{"attribute_name":"著者(ヨミ)","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"ヨコヤマ, ヒサナガ"}]},{"nameIdentifiers":[{},{}],"names":[{"name":"ウメザワ, オサム"}]},{"nameIdentifiers":[{}],"names":[{"name":"ナガイ, コトブ"}]},{"nameIdentifiers":[{}],"names":[{"name":"スズキ, タカシ"}]},{"nameIdentifiers":[{}],"names":[{"name":"コクボ, クニオ"}]}]},"item_2_publisher_35":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"ASM International"}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA10987657","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"10735623","subitem_source_identifier_type":"ISSN"}]},"item_2_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Department of Mechanical Engineering, Kogakuin University"},{"subitem_text_value":"Frontier Research Center for Structural Materials, National Research Institute for Metals"},{"subitem_text_value":"Frontier Research Center for Structural Materials, National Research Institute for Metals"},{"subitem_text_value":"Department of Mechanical Engineering, Kogakuin University"},{"subitem_text_value":"Department of Mechanical Engineering, Kogakuin 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":"Yokoyama, Hisanaga"}],"nameIdentifiers":[{"nameIdentifier":"17808","nameIdentifierScheme":"WEKO"}]},{"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":"Nagai, Kotobu"}],"nameIdentifiers":[{"nameIdentifier":"17810","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Suzuki, Takashi"}],"nameIdentifiers":[{"nameIdentifier":"17811","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kokubo, Kunio"}],"nameIdentifiers":[{"nameIdentifier":"17812","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":"2016-09-16"}],"displaytype":"detail","filename":"A-33 MMT31A11.pdf","filesize":[{"value":"4.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"A-33 MMT31A11.pdf","url":"https://ynu.repo.nii.ac.jp/record/3988/files/A-33 MMT31A11.pdf"},"version_id":"60057a03-fb9d-4f4a-9609-f1c490014cf6"}]},"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":"Cyclic deformation, dislocation structure, and internal fatigue crack generation in a Ti-Fe-O alloy at liquid nitrogen temperature","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Cyclic deformation, dislocation structure, and internal fatigue crack generation in a Ti-Fe-O alloy at liquid nitrogen temperature"}]},"item_type_id":"2","owner":"3","path":["496"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-03-23"},"publish_date":"2012-03-23","publish_status":"0","recid":"3988","relation_version_is_last":true,"title":["Cyclic deformation, dislocation structure, and internal fatigue crack generation in a Ti-Fe-O alloy at liquid nitrogen temperature"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-20T20:10:34.195012+00:00"}
