However, the stress relaxation characteristic\u2014an essential parameter as a conductor material\u2014and the effect of the material structure have not been reported, which was the aim of the present paper. An Al-5%Fe alloy was selected as the test material. The material structures were controlled by hot extrusion practice, annealing, and cold rolling. The Al-Fe intermetallic compound particles controlled the residual stress after the stress relaxation test via the Orowan mechanism. Decreasing the mean inter-particle distance reduces the electrical conductivity. The increase in the number of dislocations by the cold rolling increased strength at room temperature without changing electrical conductivity; however, it did not have a positive effect on the stress relaxation characteristics. The stress relaxation characteristics and the electrical conductivity of the Al-Fe alloy were superior to conventional C52100 H04 phosphor bronze when compared with the case of the same mass.<\/jats:p>","DOI":"10.3390\/ma16175949","type":"journal-article","created":{"date-parts":[[2023,8,30]],"date-time":"2023-08-30T10:30:52Z","timestamp":1693391452000},"page":"5949","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Effects of Material Structure on Stress Relaxation Characteristics of Rapidly Solidified Al-Fe Alloy"],"prefix":"10.3390","volume":"16","author":[{"given":"Ryohei","family":"Kobayashi","sequence":"first","affiliation":[{"name":"Advanced Materials Laboratory, Sumitomo Electric Industries, Ltd., Itami-shi 664-0016, Japan"},{"name":"Graduate School of Science and Engineering, University of Toyama, Toyama-shi 930-8555, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8743-2874","authenticated-orcid":false,"given":"Tatsuya","family":"Funazuka","sequence":"additional","affiliation":[{"name":"Academic Assembly Faculty of Engineering, University of Toyama, Toyama-shi 930-8555, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toru","family":"Maeda","sequence":"additional","affiliation":[{"name":"Advanced Materials Laboratory, Sumitomo Electric Industries, Ltd., Itami-shi 664-0016, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4432-1829","authenticated-orcid":false,"given":"Tomomi","family":"Shiratori","sequence":"additional","affiliation":[{"name":"Academic Assembly Faculty of Engineering, University of Toyama, Toyama-shi 930-8555, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,30]]},"reference":[{"key":"ref_1","first-page":"25","article-title":"Aluminum Alloy Plates and Sheets for Electrical Connection Parts","volume":"65","author":"Kaneda","year":"2015","journal-title":"Kobe Steel Eng.
