The results are as follows: (1) From the analysis of acoustic emission signals, two characteristic points (A and B points) were found. The first A-point corresponds to the initiation of slow crack growth, and the second B-point the initial deviation of crack opening displacement. These results were also verified by the observation with microscope and crack gauge. (2) The load of A-point was almost 60%of maximum load and that of B-point was 80-90%, while the load of K_<IC> value was 93-95% of maximum load. These results suggest that acoustic emission technique is a most sensitive one to detect slow crack growth. (3) There exists planer anisotropy in this alloy. J_<IC> value defined by A point had the anisotropy, which corresponds to the inclination of COD_<crit>, but not to that of K_<IC>.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA0124661000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学宇宙航空研究所"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0563-8100","subitem_source_identifier_type":"ISSN"}]},"item_9_source_id_24":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00161914","subitem_source_identifier_type":"NCID"}]},"item_9_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学宇宙航空研究所"},{"subitem_text_value":"東京大学宇宙航空研究所"},{"subitem_text_value":"東京大学宇宙航空研究所"},{"subitem_text_value":"日産自動車 宇宙航空部"},{"subitem_text_value":"日産自動車 宇宙航空部"}]},"item_9_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Aeronautical Science University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Aeronautical Science University of Tokyo"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Aeronautical Science University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"斎藤, 敏"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"岸, 輝雄"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"堀内, 良"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"中之瀬, 恩"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"垣見, 恒男"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"SAITO, S.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KISHI, T.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"HORIUCHI, R.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NAKANOSE, M.","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"KAKIMI, T.","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-01-23"}],"displaytype":"detail","filename":"SA0124661.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA0124661.pdf","url":"https://jaxa.repo.nii.ac.jp/record/31667/files/SA0124661.pdf"},"version_id":"f6ecb8d5-ad7d-48bc-a892-82c94a88a7c7"}]},"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":"球形ロケットチャンバ用チタン合金の破壊靭性値とAcoustic Emission","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"球形ロケットチャンバ用チタン合金の破壊靭性値とAcoustic Emission"}]},"item_type_id":"9","owner":"1","path":["1890","1910"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"31667","relation_version_is_last":true,"title":["球形ロケットチャンバ用チタン合金の破壊靭性値とAcoustic Emission"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T00:53:49.219970+00:00"}
