The transformation of the mechanical properties and the microstructures with varing carburized depth and hardening processes were investigated. The strength properties were improved with increasing caburized depth, but the elongation and the reduction of area were decreased markedly as quenched into water and oil in secondary quenching. In the carburizing of 5 hours the maximum hardness of the case was seven times the hardness of material as quenched into water in secondary quenching. In the test piece for tensile test quenched into water and oil as secondary quenching the quasi-cleavage fracture was observed.","subitem_description_type":"Abstract"}]},"item_2_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長野工業高等専門学校"}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00179170","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0286-1909","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_20":{"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":"堀内, 富雄"}],"nameIdentifiers":[{"nameIdentifier":"993","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小林, 義一"}],"nameIdentifiers":[{"nameIdentifier":"994","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":"2013-02-19"}],"displaytype":"detail","filename":"nagano_nct-28-04.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"nagano_nct-28-04.pdf","url":"https://nagano-nct.repo.nii.ac.jp/record/412/files/nagano_nct-28-04.pdf"},"version_id":"18ac5aa1-b282-495d-84cb-b9650ebba8f7"}]},"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":"低炭素鋼の機械的性質と組織に及ぼす浸炭硬化処理の影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"低炭素鋼の機械的性質と組織に及ぼす浸炭硬化処理の影響"}]},"item_type_id":"2","owner":"17","path":["29"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-02-19"},"publish_date":"2013-02-19","publish_status":"0","recid":"412","relation_version_is_last":true,"title":["低炭素鋼の機械的性質と組織に及ぼす浸炭硬化処理の影響"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-06-20T16:08:37.140820+00:00"}
