Both the tests were performed with a compact tension specimen by using a program-load-controlled 0.98MN fatigue testing machine. The main results obtained are summarized as follows: (1) Fatigue crack propagation rate in weld metal zone is very larger than that in both base metal and HAZ (heat affected zone.) On the contrary, fatigue life, <special>Nƒ</special> in weld metal zone is lower than a half-value of that in both base metal and HAZ. (2) Within the temperature range from 98K to room temperature, the power coeffinient, n of da/dN=A⊿<special>Kn</special> is related with 1/T as n=<special>b1</special>+<special>a1</special>/kT, and da/dN shows Arrhenius type. Apparent activation energy, Q is related with ⊿K as Q=U-<special>a1ln⊿K</special> within the same tremperature range. These trends are in good agreement with the dislocation dynamics theory of fatigue crack propagation. (3) Fatigue fracture toughness, <special>KƒC</special> and fracture toughness, <special>KC</special> in base metal are larger than those in both weld metal zone and HAZ.","subitem_description_type":"Abstract"}]},"item_4_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学教育学部"}]},"item_4_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0389-9225","subitem_source_identifier_type":"PISSN"}]},"item_4_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00234199","subitem_source_identifier_type":"NCID"}]},"item_4_text_18":{"attribute_name":"その他のタイトル","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Fatigue Crack Propagation Characteristic and Fatigue Fracture Toughness in 5.5% Ni Steel Weldments at Low Temperature"}]},"item_4_text_65":{"attribute_name":"資源タイプ（三重大）","attribute_value_mlt":[{"subitem_text_value":"Departmental Bulletin Paper / 紀要論文"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"佐藤, 清","creatorNameLang":"ja"},{"creatorName":"Sato, Kiyoshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"五十嵐, 寛","creatorNameLang":"ja"},{"creatorName":"Igarashi, Hiroshi","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"低温における5.5%Ni鋼の溶接各部における疲労き裂伝播特性および疲労破壊靭性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"低温における5.5%Ni鋼の溶接各部における疲労き裂伝播特性および疲労破壊靭性","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"13","path":["254"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2018-03-16"},"publish_date":"2018-03-16","publish_status":"0","recid":"3107","relation_version_is_last":true,"title":["低温における5.5%Ni鋼の溶接各部における疲労き裂伝播特性および疲労破壊靭性"],"weko_creator_id":"13","weko_shared_id":-1},"updated":"2023-11-07T06:18:00.202729+00:00"}
