The novel structure has an ABACAB-type six layered packing with lattice parameters of a = 0.322 nm and c = 3 ~ 0.521 nm. The Mg solid solution has fine grain sizes of 100 to 150 nm and contains 0.78 at.% Zn and 1.82 at.% Y. In addition, cubic Mg24Y5 particles with a size of about 7 nm are dispersed at small volume fractions of less than 10% in the Mg matrix. The specific density (ƒÏ) of the extruded bulk Mg-Zn-Y alloy was 1.84 Mg/m3. The tensile yield strength (ƒÐy) and elongation (ƒÂ) are 610 MPa and 5%, respectively, at room temperature, and the specific yield strength defined by the ratio of ƒÐy to ƒÏ is as high as 3.3 ~ 105 Nm/kg. High ƒÐy values exceeding 400 MPa are also maintained at temperatures up to 473 K. It is noticed that the ƒÐy levels are 2.5 to 5 times higher than those for conventional high-strength type Mg-based alloys. The Mg-based alloy also exhibits a high-strain-rate superplasticity with large ƒÂ of 700 to 800% at high strain rates of 0.1 to 0.2 s-1 and 623 K. The excellent mechanical properties are due to the combination of the fine grain size, new long periodic hexagonal solid solution containing Y and Zn, and dispersion of fine Mg24Y5 particles. The new Mg-based alloy is expected to be used in many fields.","subitem_description_type":"Other"}]},"item_16_publisher_36":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Materials Research Society"}]},"item_16_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1557/JMR.2001.0260","subitem_relation_type_select":"DOI"}}]},"item_16_relation_16":{"attribute_name":"情報源(ISSN)","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"08842914"}]}]},"item_16_relation_53":{"attribute_name":"著作の一部","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"http://www.mrs.org/s_mrs/sec_jmr.asp?CID=30&DID=48"}]}]},"item_16_rights_12":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2001 Materials Research Society"}]},"item_16_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA10664454","subitem_source_identifier_type":"NCID"}]},"item_16_subject_20":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"501","subitem_subject_scheme":"NDC"}]},"item_16_text_18":{"attribute_name":"形態","attribute_value_mlt":[{"subitem_text_value":"623753 bytes"}]},"item_16_text_47":{"attribute_name":"資源タイプ・ローカル","attribute_value_mlt":[{"subitem_text_value":"雑誌掲載論文"}]},"item_16_text_48":{"attribute_name":"資源タイプ・NII","attribute_value_mlt":[{"subitem_text_value":"Journal Article"}]},"item_16_text_49":{"attribute_name":"資源タイプ・DCMI","attribute_value_mlt":[{"subitem_text_value":"text"}]},"item_16_text_50":{"attribute_name":"資源タイプ・ローカル表示コード","attribute_value_mlt":[{"subitem_text_value":"01"}]},"item_16_version_type_19":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Inoue, Akihisa"}],"nameIdentifiers":[{"nameIdentifier":"96578","nameIdentifierScheme":"WEKO"}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":"","affiliationNameIdentifierScheme":"ISNI","affiliationNameIdentifierURI":"http://www.isni.org/isni/"}],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"河村, 能人","creatorNameLang":"ja"},{"creatorName":"カワムラ, ヨシヒト","creatorNameLang":"ja-Kana"},{"creatorName":"Kawamura, Yoshihito","creatorNameLang":"en"}],"familyNames":[{"familyName":"河村","familyNameLang":"ja"},{"familyName":"カワムラ","familyNameLang":"ja-Kana"},{"familyName":"Kawamura","familyNameLang":"en"}],"givenNames":[{"givenName":"能人","givenNameLang":"ja"},{"givenName":"ヨシヒト","givenNameLang":"ja-Kana"},{"givenName":"Yoshihito","givenNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"165058","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Matsushita, Mitsuhide"}],"nameIdentifiers":[{"nameIdentifier":"96580","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hayashi, Kentaro"}],"nameIdentifiers":[{"nameIdentifier":"96581","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Koike, Junichi"}],"nameIdentifiers":[{"nameIdentifier":"96582","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-03-02"}],"displaytype":"detail","filename":"JMR-16.pdf","filesize":[{"value":"623.8 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"JMR-16.pdf","url":"https://kumadai.repo.nii.ac.jp/record/22213/files/JMR-16.pdf"},"version_id":"21282a23-05ab-4b4d-a8db-72dfdfb1db38"}]},"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":"Novel hexagonal structure and ultrahigh strength of magnesium solid solution in the Mg-Zn-Y system","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Novel hexagonal structure and ultrahigh strength of magnesium solid solution in the Mg-Zn-Y system"}]},"item_type_id":"16","owner":"1","path":["428"],"pubdate":{"attribute_name":"公開日","attribute_value":"2009-02-25"},"publish_date":"2009-02-25","publish_status":"0","recid":"22213","relation_version_is_last":true,"title":["Novel hexagonal structure and ultrahigh strength of magnesium solid solution in the Mg-Zn-Y system"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-09-05T06:46:35.375636+00:00"}
