Application of HPT processing at RT and 150°C under an applied pressure of 5 GPa for 10 revolutions at 1 rpm to alloy specimens (RT- and 150°C-specimen) produces an ultra-fine grained structure with a grain size of 70 nm. The hardnesses of the RT- and 150°C-specimens increase with equivalent strain up to 7 and then saturate at constant values of 400 and 430 Hv, respectively. Annealing the RT-specimen at 150°C for 10 min increases the hardness from 400 to 430 Hv. Transmission electron microscopy observations of the 150°C-specimen and the RT-specimen annealed at 150°C reveal that there are no intragranular and intergranular precipitates. It is suggested that the higher hardness of the 150°C-specimen than the RT-specimen is ascribed to the segregation of Be atoms on dislocations during HPT processing at 150°C. The RT- and 150°Cspecimens harden rapidly and exhibit maximum values of hardness at 3 min during aging at 320°C. The increase in the hardness is attributed to the precipitation of finely dispersed G.P. zones. © (2014) Trans Tech Publications, Switzerland.","subitem_description_type":"Abstract"}]},"item_4_publisher_17":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Trans Tech Publications"}]},"item_4_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.4028/www.scientific.net/MSF.783-786.2707","subitem_relation_type_select":"DOI"}}]},"item_4_source_id_11":{"attribute_name":"NCID","attribute_value_mlt":[{"subitem_source_identifier":"AA12159099","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1022-6680","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_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Watanabe, Chihiro"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"Monzen, Ryoichi"}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"Ii, Seiichiro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Tsuchiya, Koichi"}],"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-WATANABE-C-2707.pdf","filesize":[{"value":"563.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"TE-PR-WATANABE-C-2707.pdf","url":"https://kanazawa-u.repo.nii.ac.jp/record/9140/files/TE-PR-WATANABE-C-2707.pdf"},"version_id":"bdc3bc7a-8108-41d6-a151-d23bac159e06"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Microstructure and aging behavior of Cu-Be alloy processed by high-pressure torsion","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Microstructure and aging behavior of Cu-Be alloy processed by high-pressure torsion"}]},"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":"9140","relation_version_is_last":true,"title":["Microstructure and aging behavior of Cu-Be alloy processed by high-pressure torsion"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-07-28T01:58:24.903392+00:00"}
