The most suitable heat treatment for obtaining the best magnetic properties of this magnet steel is primary heating at 600℃&acd;900℃ and subsequent heating for 15 mins. at 1060℃ followed by air-cooling. During the air-cooling from 1060℃, a large number of fine spherical carbides precipitate, whereas water-quenching from 1060℃ supresses the precipitation of the fine carbides. By the primary heating followed by the air-cooling from 1060℃, the quantity of the retained austenite is decreased and the precipitation of the fine spherical carbides promoted. When water-quenched specimen is tempered at 300℃, the fine spherical carbides are found to precipitate. Both coercive force and residual induction of the specimen are increased, whereas hardness is decreased by the precipitation of the fine carbides. The coercive force of the magnet steel of the present study seems to be due to the magnetization fluctuation of the martensite which fluctuation is caused by the precipitation of a large number of fine spherical carbides and also to the internal stress in the martensite. The magnetic properties of this magnet steel is improved by addition of Co and W.","subitem_description_type":"Other"}]},"item_9_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: SA2404782000","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_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"Aeronautical Research Institute, University of Tokyo"}]},"item_9_source_id_21":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0376-1061","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":"AA00514444","subitem_source_identifier_type":"NCID"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"TACHIKAWA, Kyoji","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":"SA2404782.pdf","filesize":[{"value":"1.9 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SA2404782.pdf","url":"https://jaxa.repo.nii.ac.jp/record/34583/files/SA2404782.pdf"},"version_id":"c276b837-a423-462b-b459-10018dd39351"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"The Magnetic Properties and the Microstructure of High-C, High-Cr Magnet Steel","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"The Magnetic Properties and the Microstructure of High-C, High-Cr Magnet Steel","subitem_title_language":"en"}]},"item_type_id":"9","owner":"1","path":["1890","1901"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"34583","relation_version_is_last":true,"title":["The Magnetic Properties and the Microstructure of High-C, High-Cr Magnet Steel"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-20T23:39:03.573454+00:00"}
