The MA process results in homogeneous amorphous phases of BaFe2As2 and SrFe2As2. It was found that the optimum time for high-energy milling in all cases is about 1.5\u20132 h, and the maximum amount of amorphous phase could be obtained when energy of 50\u2013100 MJ\/kg was absorbed by the powder. After a short-term heat treatment, we obtained nearly optimum sodium-doped Ba1\u2212xNaxFe2As2 and Sr1\u2212xNaxFe2As2 superconducting bulk samples. Therefore, MA is a potential scalable method to produce bulk superconducting material for industrial needs.<\/jats:p>","DOI":"10.3390\/ma15238438","type":"journal-article","created":{"date-parts":[[2022,11,28]],"date-time":"2022-11-28T07:38:49Z","timestamp":1669621129000},"page":"8438","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Phase Formation of Iron-Based Superconductors during Mechanical Alloying"],"prefix":"10.3390","volume":"15","author":[{"given":"Vladimir A.","family":"Vlasenko","sequence":"first","affiliation":[{"name":"V.L.
