They were stressed by grain-boundary sliding at 548K or directly by external stress at 77K to study the stress-induced martensitic transformation from fcc to bcc. No plastic deformation due to crystal dislocation activity occurred during these loading processes. Larger particles transformed to bcc when they were cooled to 77K or were stressed by the external stress at 77K.Some particular variants of martensite were preferentially formed under the internal stress caused by boundary sliding or depending on the sense (tension or compression) and direction ([416]_f or [001]_f) of the applied stress. The preferential formation of the variants could be explained well by postulating that the stress helps the shear movement of atoms to change the lattice from fcc to bcc. No accelerating effect of a large pre-existing hydrostatic stress, caused by the lattice parameter difference between gamma-Fe and Cu, on the transformation is also consistent with this contention. Any effect of the stress on the overall shape strain has been excluded.","subitem_description_type":"Abstract"}]},"item_9_description_22":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:07650762, 研究期間(年度):1995-1996","subitem_description_type":"Other"},{"subitem_description":"出典：「銅粒界上γ-Fe粒子の応力誘起マルテンサイト変態」研究成果報告書　課題番号07650762\n  (KAKEN：科学研究費助成事業データベース（国立情報学研究所）)\n　　　本文データは著者版報告書より作成","subitem_description_type":"Other"}]},"item_9_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24517/00052642","subitem_identifier_reg_type":"JaLC"}]},"item_9_publisher_17":{"attribute_name":"公開者","attribute_value_mlt":[{"subitem_publisher":"金沢大学理工研究域機械工学系"}]},"item_9_relation_28":{"attribute_name":"関連URI","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/search/?qm=20166466"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/search/?qm=20166466","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-07650762/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/grant/KAKENHI-PROJECT-07650762/","subitem_relation_type_select":"URI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-07650762/076507621996kenkyu_seika_hokoku_gaiyo/"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://kaken.nii.ac.jp/report/KAKENHI-PROJECT-07650762/076507621996kenkyu_seika_hokoku_gaiyo/","subitem_relation_type_select":"URI"}}]},"item_9_version_type_25":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-11-01"}],"displaytype":"detail","filename":"TE-PR-MONZEN-R-kaken 1997-10p.pdf","filesize":[{"value":"198.1 kB"}],"format":"application/pdf","licensetype":"license_11","mimetype":"application/pdf","url":{"label":"TE-PR-MONZEN-R-kaken 1997-10p.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/46309/files/TE-PR-MONZEN-R-kaken 1997-10p.pdf"},"version_id":"410034ee-b9c2-459f-8aa7-1aab2eefc606"}]},"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":"research report","resourceuri":"http://purl.org/coar/resource_type/c_18ws"}]},"item_title":"銅粒界上γ-Fe粒子の応力誘起マルテンサイト変態","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"銅粒界上γ-Fe粒子の応力誘起マルテンサイト変態"},{"subitem_title":"Stress-Induced Martensitic Transformation of Boundary gamma-Fe Particles in Cu","subitem_title_language":"en"}]},"item_type_id":"9","owner":"18","path":["2837"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-11-01"},"publish_date":"2018-11-01","publish_status":"0","recid":"46309","relation_version_is_last":true,"title":["銅粒界上γ-Fe粒子の応力誘起マルテンサイト変態"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2023-07-27T14:53:27.098341+00:00"}
