Within strain rates of 6.6×10^<-6>S^<-1> for intergranular cracking and of 1.1×10^<-5>S^<-1> for transgranular cracking, the rate-controlling step of stress-corrosion cracking corresponds to the slip step formation. Exceeding the above strain rates the scc is controlled by the corrosion, where the rate-controlling mechanism requires the activation energy of about 18.7 Kcal/mol. When the strain rate exceeds 1.1×10^<-3>S^<-1>, intergranular scc never occurs at room temperature. Width of crack tip increases with increase of strain rate for intergranular cracking, while decreases for transgranular cracking.","subitem_description_type":"Abstract"}]},"item_4_description_41":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"subitem_description":"紀要類(bulletin)","subitem_description_type":"Other"}]},"item_4_description_66":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"32824 bytes","subitem_description_type":"Other"}]},"item_4_publisher_34":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Tohoku University"}]},"item_4_radio_69":{"attribute_name":"公開範囲","attribute_value_mlt":[{"subitem_radio_item":"学外"}]},"item_4_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00408808","subitem_source_identifier_type":"ISSN"}]},"item_4_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00836167","subitem_source_identifier_type":"NCID"}]},"item_4_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":"TAKANO, Michinori"}],"nameIdentifiers":[{"nameIdentifier":"108044","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":"2017-02-16"}],"displaytype":"detail","filename":"KJ00004197856.pdf","filesize":[{"value":"32.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00004197856.pdf","url":"https://tohoku.repo.nii.ac.jp/record/46166/files/KJ00004197856.pdf"},"version_id":"d3b374fd-cb7f-4fe7-9bac-f13c7d638d51"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Relationship between Stress-Corrosion Cracking and Strain Rate in Alpha Brass","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Relationship between Stress-Corrosion Cracking and Strain Rate in Alpha Brass"}]},"item_type_id":"4","owner":"3","path":["267"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-05-02"},"publish_date":"2008-05-02","publish_status":"0","recid":"46166","relation_version_is_last":true,"title":["Relationship between Stress-Corrosion Cracking and Strain Rate in Alpha Brass"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-07-27T15:11:11.973303+00:00"}
