The distribution of the half-value breadth of X-ray diffraction profiles beneath the fracture surface was determined. Based on those results and electron fractographic observation, the mechanism of fracture in ductile cast iron was discussed as a function of test temperature. The main results are summarized as follows : (1) The size of the plastic zone ω_y determined from the half-value breadth distribution is related to the fracture toughness K_i through ω_y=0.13(K_i/σ_Y)^2 where σ_Y is the yield stress. (2) The fracture toughness decreased with lowering temperature and the fracture mode of the matrix changed from dimples to cleavage. The unique relation was established between the fracture surface strain and K^2_i/σ_Y.","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"},{"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/110002300487/","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":"矢島, 善次郎"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"広瀬, 幸雄"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"田中, 啓介"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"小河, 弘"}],"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-1345.pdf","filesize":[{"value":"681.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"TE-PR-HIROSE-Y-1345.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/8346/files/TE-PR-HIROSE-Y-1345.pdf"},"version_id":"48bda54c-e901-427c-a4e6-407984dabf14"}]},"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":"球状黒鉛鋳鉄の低温における破壊じん性のX線フラクトグラフィ的研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"球状黒鉛鋳鉄の低温における破壊じん性のX線フラクトグラフィ的研究"},{"subitem_title":"X-Ray Fractographic Study on Fracture Toughness of Ductile Cast Iron at Low Temperatures","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":"8346","relation_version_is_last":true,"title":["球状黒鉛鋳鉄の低温における破壊じん性のX線フラクトグラフィ的研究"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-28T02:10:14.582851+00:00"}
