Fatigue crack growth tests were carried out over a wide range of fatigue crack growth rate covering the threshold stress intensity factor range ΔK_<th>. The fatigue tests were conducted at 10Hz and two stress ratios R=0.1 and 0.5 in laboratory air at room temperature using the 3-point bending specimens. It was found that the crack growth rate da/dN against the stress intensity factor range ΔK depended on stress ratio R. The crack growth rate plotted in terms of the effective stress intensity factor range ΔK_<eff> (after allowing for crack closure) still exhibited the effect of microstructure. Fractographic examination revealed brittle fracture at R=0.1 and ductile fracture at R=0.5 in Co binder phase. The amount of Co phase transformation was closely related to the fatigue crack growth characteristics.","subitem_description_type":"Abstract"}]},"item_4_description_5":{"attribute_name":"提供者所属","attribute_value_mlt":[{"subitem_description":"金沢大学大学院自然科学研究科","subitem_description_type":"Other"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本材料学会"}]},"item_4_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://ci.nii.ac.jp/naid/110002293215/","subitem_relation_type_select":"URI"}}]},"item_4_rights_23":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"日本材料学会；本文データは日本材料学会の許諾に基づきCiNiiから複製したものである"}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AN00096175","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0514-5163","subitem_source_identifier_type":"ISSN"}]},"item_4_version_type_25":{"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":"広瀬, 幸雄"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"夫, 明煥"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"松岡, 秀明"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"朴, 栄哲"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-10-03"}],"displaytype":"detail","filename":"TE-PR-HIROSE-Y-1402.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"TE-PR-HIROSE-Y-1402.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/9808/files/TE-PR-HIROSE-Y-1402.pdf"},"version_id":"5af01520-f8de-4730-bcaf-b57ebc5a17ec"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"WC-Co超硬合金の疲労き裂進展特性に及ぼす応力比およびWC粒径の影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"WC-Co超硬合金の疲労き裂進展特性に及ぼす応力比およびWC粒径の影響"},{"subitem_title":"Influence of Stress Ratio and WC Grain Size on Fatigue Crack Growth Characteristics of WC-Co Cemented Carbides","subitem_title_language":"en"}]},"item_type_id":"4","owner":"3","path":["936"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-10-03"},"publish_date":"2017-10-03","publish_status":"0","recid":"9808","relation_version_is_last":true,"title":["WC-Co超硬合金の疲労き裂進展特性に及ぼす応力比およびWC粒径の影響"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-28T01:48:50.176370+00:00"}
