Some kinds of specimen possessed key grooves and some did not. Paticularly, the materials with key grooves used in this experiment possessed the various depths of induction hardening. The fracture surfaces were investigated by means of an electron microscope. The conculusions obtained are as follows: (1) Fatigue limits (1×10＾7cycle) increased about 13.6% at the material A(deep induction hardening steel), about 21.6% at the material B(shallow induction hardening steel), and about 8.16% at the material C(steel with no induction hardening). Fatigue limits mentioned above were caluculated using fatigue limits of the materials of key grooves as standard of calculation. (2) The crack propagation patterns of fatigue was observed in the key groove. In particular, the meterial A was observed to have crack propagation to the direction of 45 degrees from the root of the key groove.","subitem_description_type":"Abstract"}]},"item_2_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"長野工業高等專門学校"}]},"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":"芳賀, 武"}],"nameIdentifiers":[{"nameIdentifier":"1370","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"西村, 博之"}],"nameIdentifiers":[{"nameIdentifier":"1371","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"関川, 三男"}],"nameIdentifiers":[{"nameIdentifier":"1372","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":"2013-02-21"}],"displaytype":"detail","filename":"nagano_nct-19-02.pdf","filesize":[{"value":"1.2 MB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"nagano_nct-19-02.pdf","url":"https://nagano-nct.repo.nii.ac.jp/record/646/files/nagano_nct-19-02.pdf"},"version_id":"d4a5c0f8-7cc6-4ae8-98a1-d7b86fb83bf6"}]},"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":"キー溝を有する高周波焼入れ鋼(S45C)の回転曲げ疲労強度","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"キー溝を有する高周波焼入れ鋼(S45C)の回転曲げ疲労強度"}]},"item_type_id":"2","owner":"17","path":["41"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-02-21"},"publish_date":"2013-02-21","publish_status":"0","recid":"646","relation_version_is_last":true,"title":["キー溝を有する高周波焼入れ鋼(S45C)の回転曲げ疲労強度"],"weko_creator_id":"17","weko_shared_id":-1},"updated":"2023-06-20T15:59:12.596784+00:00"}
