Bending plasticity and Vickers hardness and optical micrographs were studied. The Vickers hardness number versus annealing temperature curve (annealing time=const=1 hour) show at least three maxima in the temperature range over 200℃; the maximum that occurs just prior to recrystallization is probably related with polygonization, the two maxima that precede the above-mentioned maximum are related with the so-called anneal-hardening. On the microscopic photographs of nickel silver sheets that were annealed at 800℃ for. 1 hr. and then cold-rolled, many large grains that are oblong along the direction of rolling were found, but none on those of nickel silver sheets that were annealed at 650℃ for 1 hr and then cold-rolled. In this occasion effect of low temperature annealing on cold-rolled sheets of pure copper (see Table 2) was studied, and a curve similar to Fig.18 of reference 8 was again obtained, indicating that hardening by annealing can take place in pure copper sheets. This can be interpreted to be due to the small mobility of dislocations caused by the grain boundaries. The anneal-hardening phenomena observed in cold-rolled brass and nickel silver sheets would be explained similarly.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA4134962000","subitem_description_type":"Other"}]},"item_9_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学航空研究所"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0563-8097","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":"AN00162214","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"村川, 洯"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Murakawa, Kiyoshi","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":"2020-01-24"}],"displaytype":"detail","filename":"SA4134962.pdf","filesize":[{"value":"974.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA4134962.pdf","url":"https://jaxa.repo.nii.ac.jp/record/35096/files/SA4134962.pdf"},"version_id":"2f4b5c15-d186-4590-861c-5570f9247f75"}]},"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":"洋白板および純銅板における低温焼鈍効果","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"洋白板および純銅板における低温焼鈍効果"}]},"item_type_id":"9","owner":"1","path":["1890","1909"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"35096","relation_version_is_last":true,"title":["洋白板および純銅板における低温焼鈍効果"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T23:26:55.185243+00:00"}
