The diameter of the resultant alloys was in the range of 150 micrometer to 2,000 micrometer. The relationship between the sample size and microstructure was investigated. When the diameter of a spherical sample was larger than 500 micrometer, the microstructure of the sample consisted of the alpha-Fe dendrite with the Nd2Fe14B matrix. In the sample with 400 micrometer in diameter consisted two regions; one is the alpha-Fe dendrite with Nd2Fe14B matrix, and the other is the Nd2Fe14B columnar and Nd-rich grain boundary. The Nd2Fe14B columnar region expanded as the sample diameter decreased from 400 micrometer to 350 micrometer. In the spherical sample whose diameter is reduced to 250 micrometer, the microstructure consists of only Nd2Fe14B dendrites.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号: AA0045438063","subitem_description_type":"Other"}]},"item_5_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宇宙科学研究所"}]},"item_5_publisher_9":{"attribute_name":"出版者（英）","attribute_value_mlt":[{"subitem_publisher":"The Institute of Space and Astronautical Science (ISAS)"}]},"item_5_text_6":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"宇宙科学研究所"},{"subitem_text_value":"宇宙科学研究所"},{"subitem_text_value":"東海大学"},{"subitem_text_value":"東海大学"}]},"item_5_text_7":{"attribute_name":"著者所属（英）","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Astronautical Science"},{"subitem_text_language":"en","subitem_text_value":"Institute of Space and Astronautical Science"},{"subitem_text_language":"en","subitem_text_value":"Tokai University"},{"subitem_text_language":"en","subitem_text_value":"Tokai University"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"小澤, 俊平"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"栗林, 一彦"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"神保, 至"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"杉山, 卓"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Ozawa, Shunpei","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kuribayashi, Kazuhiko","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Jinbo, Itaru","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Sugiyama, Suguru","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"無容器凝固","subitem_subject_scheme":"Other"},{"subitem_subject":"落下塔","subitem_subject_scheme":"Other"},{"subitem_subject":"Nd2Fe14B樹皮状結晶","subitem_subject_scheme":"Other"},{"subitem_subject":"微細構造","subitem_subject_scheme":"Other"},{"subitem_subject":"核形成","subitem_subject_scheme":"Other"},{"subitem_subject":"プラントル数","subitem_subject_scheme":"Other"},{"subitem_subject":"X線回折","subitem_subject_scheme":"Other"},{"subitem_subject":"過冷却","subitem_subject_scheme":"Other"},{"subitem_subject":"containerless solidification","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"drop tower","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Nd2Fe14B dendrite","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"microstructure","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"nucleation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Prandtl number","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"X-ray diffraction","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"supercooling","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"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":"conference paper","resourceuri":"http://purl.org/coar/resource_type/c_5794"}]},"item_title":"25mドロップチューブを利用した急速凝固NdFeB合金の凝固組織","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"25mドロップチューブを利用した急速凝固NdFeB合金の凝固組織"}]},"item_type_id":"5","owner":"1","path":["1648","1891"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-03-26"},"publish_date":"2015-03-26","publish_status":"0","recid":"13970","relation_version_is_last":true,"title":["25mドロップチューブを利用した急速凝固NdFeB合金の凝固組織"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-06-21T05:41:55.150630+00:00"}
