Recent HEA-related research aimed toward identifying the effect that certain alloying elements in different concentrations influence the microstructure and properties but also regulate their composition. HEAs present promising properties (e.g., corrosion and wear resistance) being applicable in domains that require protection against harsh environmental conditions, benefiting from the specific core effects of this type of material. To obtain a high alloying and homogenization degree, for this research, mechanical alloying was selected for processing the mixtures, with the aid of N-Heptane as a process control agent (PCA). The mixtures were monitored in terms of alloying degree evolution, elemental distribution, particle morphology, crystalline structure, and also technological characterization (packing ratio, free flow, and slope angle). The results indicated that a high degree of alloying was obtained after 30 h of solid-state processing, with notable crystallization of two major phases FCC and BCC identified confirming the HEA phase stability calculations.<\/jats:p>","DOI":"10.3390\/ma18091936","type":"journal-article","created":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T08:08:41Z","timestamp":1745482121000},"page":"1936","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Effect of Co and Al Content on CrFeNiMo-System High Entropy Alloys Produced by Mechanical Alloying"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5641-4905","authenticated-orcid":false,"given":"Laura Elena","family":"Geambazu","sequence":"first","affiliation":[{"name":"National Institute for R&D in Electrical Engineering ICPE-CA Bucharest, Splaiul Unirii 313, 030138 Bucharest, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9437-4051","authenticated-orcid":false,"given":"Ciprian Alexandru","family":"Manea","sequence":"additional","affiliation":[{"name":"National Institute for R&D in Electrical Engineering ICPE-CA Bucharest, Splaiul Unirii 313, 030138 Bucharest, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ileana Mariana","family":"Mate\u0219","sequence":"additional","affiliation":[{"name":"Faculty of Materials Science and Engineering, National University for Science & Technology Politehnica Bucharest, 313 Splaiul Independentei, 060042 Bucharest, Romania"},{"name":"Central Military Emergency University Hospital \u201cDr. Carol Davila\u201d, Calea Plevnei 134, 010825 Bucharest, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1579-423X","authenticated-orcid":false,"given":"Delia","family":"P\u0103troi","sequence":"additional","affiliation":[{"name":"National Institute for R&D in Electrical Engineering ICPE-CA Bucharest, Splaiul Unirii 313, 030138 Bucharest, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gabriela Beatrice","family":"Sb\u00e2rcea","sequence":"additional","affiliation":[{"name":"National Institute for R&D in Electrical Engineering ICPE-CA Bucharest, Splaiul Unirii 313, 030138 Bucharest, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eugen","family":"Manta","sequence":"additional","affiliation":[{"name":"National Institute for R&D in Electrical Engineering ICPE-CA Bucharest, Splaiul Unirii 313, 030138 Bucharest, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6864-3297","authenticated-orcid":false,"given":"Augustin","family":"Semenescu","sequence":"additional","affiliation":[{"name":"Faculty of Materials Science and Engineering, National University for Science & Technology Politehnica Bucharest, 313 Splaiul Independentei, 060042 Bucharest, Romania"},{"name":"Academy of Romanian Scientists, 3 Ilfov St., 050044 Bucharest, Romania"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,4,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"204765","DOI":"10.1016\/j.wear.2023.204765","article-title":"Corrosion and corrosive wear of AlCrFeCoNi and Co-free AlCrFeNi-Tix (x = 0\u20131.5) high-entropy alloys in 3.5 wt % NaCl and H2SO4 (pH = 3) solutions","volume":"523","author":"Wu","year":"2023","journal-title":"Wear"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"162501","DOI":"10.1016\/j.jallcom.2021.162501","article-title":"Microstructure and magnetic behaviors of FeCoNi (Al) alloys with incoherent nanoprecipitates prepared by high-pressure solidification","volume":"894","author":"Chang","year":"2022","journal-title":"J.
