To study the effects of the test temperature and the loading frequency on the LCF fracture behavior in SP-700/SCS-6, the LCF tests were performed under strain-controlled condition at room temperature and 450℃. In the LCF tests two strain wave shapes were applied : the fast-fast wave in which the loading frequency was 0.5 Hz, and the slow-slow wave in which it was 1/360 Hz, respeetively. The conclusions obtained from the experimental results are summarized as follows : (1) The LCF lives of the composite were almost comparable to those of the matrix alloty, on the basis of strain range. In other words, the performace of the present composite material can be absolutely improved, since the stiffness and the deformation resistance can significantly increased by the composition. (2) The fatigue cracks were initiated from the matrix part at the specimen corner. The fiber pull-out was not so significant on the fracture surface. (3) The LCF lives of the composite at 450℃ were longer than those at room temperature. This trend was in contrast to the monolithic matrix alloy which exhibits a normal temperature dependence in the LCF lives. (4) The LCF lives of the composite under the slow-slow wave was noticeably shorter than those under the fast-fast wave at high temperature. This trend was familiar to the conventional monolithic materials.","subitem_description_type":"Abstract"}]},"item_4_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本材料学会"}]},"item_4_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0514-5163","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":"AN00096175","subitem_source_identifier_type":"NCID"}]},"item_4_version_type_15":{"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":"山崎, 泰広"}],"nameIdentifiers":[{"nameIdentifier":"2151","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"岡崎, 正和"}],"nameIdentifiers":[{"nameIdentifier":"2152","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"平野, 一美"}],"nameIdentifiers":[{"nameIdentifier":"2153","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-06-14"}],"displaytype":"simple","filename":"54(2)_187-192.pdf","filesize":[{"value":"402 KB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"url":"https://niit.repo.nii.ac.jp/record/2000268/files/54(2)_187-192.pdf"},"version_id":"21a8bc16-1b36-4000-84a0-943817cd8eda"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Titanium alloy matrix composite","subitem_subject_scheme":"Other"},{"subitem_subject":"SP-700/SCS-6","subitem_subject_scheme":"Other"},{"subitem_subject":"Isothermal low cycle fatigue (LCF)","subitem_subject_scheme":"Other"},{"subitem_subject":"Fatigue life","subitem_subject_scheme":"Other"},{"subitem_subject":"Temperature dependence","subitem_subject_scheme":"Other"},{"subitem_subject":"Loading frequence","subitem_subject_scheme":"Other"}]},"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":"SP-700/SCS-6チタン合金複合材とモノリシックなマトリックス材の低サイクル疲労破壊挙動の相違","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"SP-700/SCS-6チタン合金複合材とモノリシックなマトリックス材の低サイクル疲労破壊挙動の相違","subitem_title_language":"ja"},{"subitem_title":"Difference of Fracture Behavior on Isothermal Low Cycle Fatigue between SP-700/SCS-6 Titanium Alloy Matrix Composite and Monolithic Matrix Alloy","subitem_title_language":"en"}]},"item_type_id":"4","owner":"4","path":["32"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2011-08-05"},"publish_date":"2011-08-05","publish_status":"0","recid":"2000268","relation_version_is_last":true,"title":["SP-700/SCS-6チタン合金複合材とモノリシックなマトリックス材の低サイクル疲労破壊挙動の相違"],"weko_creator_id":"4","weko_shared_id":-1},"updated":"2025-06-10T08:28:14.225390+00:00"}
