This method considers the heats of mixing between precursor elements and a melt element to design miscible and immiscible elements for a precursor. In this study, Ni and Co were selected as the miscible elements in an Mg melt as constituents of (FeCo)100−xNix precursor alloys to understand the complex mechanisms of their dissolution behavior. Dissolution of the second miscible element, Co, was governed by the composition of the Mg melt, because the characteristics of the melt changed in the presence of a high amount of dissolved Ni and its convection. The synthesized FeCo ligaments showed morphology variations depending on the dealloying temperature: the ligaments become more elongated along the dealloying direction at higher temperatures. A double-gyroid-like porous structure with a narrow liquid channel, produced from the (FeCo)70Ni30 precursor, exhibited the highest specific surface area at all processing temperatures from 600 °C to 800 °C. This structure differed completely from that of the typical porous Fe80Cr20 alloy produced under the same liquid metal dealloying conditions. Elongation resulted from time-dependent directional coarsening behavior that was affected by the composition of the Mg melt. Keywords: Dealloying, Porous materials, Ordered FeCo, Microstructure, Double gyroid, Nano ligament"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380568467065166336","@type":"Researcher","foaf:name":[{"@value":"Soo-Hyun Joo"}]},{"@id":"https://cir.nii.ac.jp/crid/1380568467065166337","@type":"Researcher","foaf:name":[{"@value":"Takeshi Wada"}]},{"@id":"https://cir.nii.ac.jp/crid/1380568467065166338","@type":"Researcher","foaf:name":[{"@value":"Hidemi Kato"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"02641275"}],"prism:publicationName":[{"@value":"Materials & Design"}],"dc:publisher":[{"@value":"Elsevier BV"}],"prism:publicationDate":"2019-10","prism:volume":"180","prism:startingPage":"107908"},"reviewed":"false","dcterms:accessRights":"http://purl.org/coar/access_right/c_abf2","dc:rights":["https://www.elsevier.com/tdm/userlicense/1.0/","https://www.elsevier.com/legal/tdmrep-license","http://creativecommons.org/licenses/by-nc-nd/4.0/"],"url":[{"@id":"https://api.elsevier.com/content/article/PII:S0264127519303466?httpAccept=text/xml"},{"@id":"https://api.elsevier.com/content/article/PII:S0264127519303466?httpAccept=text/plain"}],"createdAt":"2019-06-01","modifiedAt":"2025-10-02","foaf:topic":[{"@id":"https://cir.nii.ac.jp/all?q=TA401-492","dc:title":"TA401-492"},{"@id":"https://cir.nii.ac.jp/all?q=Materials%20of%20engineering%20and%20construction.%20Mechanics%20of%20materials","dc:title":"Materials of engineering and construction.
