The galvanizing layer causes a reduction in the yield point, tensile strength, and fatigue strength.\nThe reduction in the fatigue strength was more significant in the high cycle fatigue at R = 0.5 and 0.01 and in the low cycle fatigue at R = 0.5. \nThe galvanizing layer seems to have very little effect on the fatigue strength at R = −1.0 in the low and high cycle fatigue. Since the fatigue strengths at R = 0.01 and −1.0 in the low cycle fatigue were strongly related to the tensile strength of the substrate, the cracking of galvanized steel was different than that of non-galvanized steel.\nThe fatigue strength of galvanized steel at R = 0.5 dropped remarkably in the low cycle fatigue in comparison to the non-galvanized steel, and many cracks clearly occurred in the galvanizing layer. The galvanizing layer reduced the fatigue strength only under tension–tension loading.\nWe believe that the findings in this study will be useful in the fatigue design of hot-dip galvanized steel."}]},"item_3_description_63":{"attribute_name":"研究課題番号","attribute_value_mlt":[{"subitem_description":"15K18232"}]},"item_3_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"MDPI"}]},"item_3_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.3390/ma14237480","subitem_relation_type_select":"DOI"}}]},"item_3_relation_13":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"Publisher's Version/PDF (OpenAccess)"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.3390/ma14237480","subitem_relation_type_select":"DOI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"MDPI"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.mdpi.com/journal/materials","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"KAKEN研究課題: 亜鉛めっき鋼材の腐食疲労に関する基礎研究"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/ja/grant/KAKENHI-PROJECT-15K18232/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"研究代表者: 盛田 元彰 (東京海洋大学)"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://nrid.nii.ac.jp/ja/nrid/1000030636626/","subitem_relation_type_select":"URI"}}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1996-1944","subitem_source_identifier_type":"ISSN"}]},"item_3_subject_62":{"attribute_name":"件名","attribute_value_mlt":[{"subitem_subject":"科学研究費研究成果"}]},"item_3_subject_64":{"attribute_name":"科学研究費研究課題","attribute_value_mlt":[{"subitem_subject":"亜鉛めっき鋼材の腐食疲労に関する基礎研究"},{"subitem_subject":"Fundamental research of corrosion fatigue at galvanized steel"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Thomas Alweendo, Shatumbu"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Morita, Motoaki"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Hasegawa, Kayo"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Motoda, Shin-ichi"}],"nameIdentifiers":[{},{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"fatigue strength","subitem_subject_scheme":"Other"},{"subitem_subject":"stress ratio","subitem_subject_scheme":"Other"},{"subitem_subject":"hot-dip galvanized steel","subitem_subject_scheme":"Other"},{"subitem_subject":"normalized steel","subitem_subject_scheme":"Other"},{"subitem_subject":"fracture surface","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"}]},"item_title":"Fatigue Properties of Hot-Dip Galvanized AISI 1020 Normalized Steel in Tension–Compression and Tension–Tension Loading","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Fatigue Properties of Hot-Dip Galvanized AISI 1020 Normalized Steel in Tension–Compression and Tension–Tension Loading"}]},"item_type_id":"3","owner":"15","path":["518","519","646","647"],"pubdate":{"attribute_name":"公開日","attribute_value":"2022-08-22"},"publish_date":"2022-08-22","publish_status":"0","recid":"2522","relation_version_is_last":true,"title":["Fatigue Properties of Hot-Dip Galvanized AISI 1020 Normalized Steel in Tension–Compression and Tension–Tension Loading"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2023-07-25T10:28:24.004744+00:00"}
