High-entropy　alloys　have　good　application　prospects　in　nuclear　power　plants　due　to　their　excellent　mechanical　properties　and　radiation　resistance.　In　this　paper,　the　microstructure　of　the　Co32　Cr28　Ni32.94　Al4.06　Ti3　high-entropy　alloy　was　researched　using　metallurgical　microscopy,　X-ray　diffraction,　and　scanning　electron　microscopy.　The　mechanical　properties　were　tested　using　a　Vickers　microhardness　tester　and　a　tensile　testing　machine,　respectively.　The　results　showed　that　Co32　Cr28　Ni32.94　Al4.06　Ti3　had　a　single-phase,　disordered,　face-centered,　cubic　solid-solution　structure　and　was　strengthened　by　solid　solution.　The　alloy　lattice　parameter　and　density　were　estimated　as　0.304　nm　and　7.89　g/cm3,　respectively.　The　test　results　indicated　that　the　alloy　had　satisfactory　mechanical　properties　with　yield　stress　and　tensile　strength　of　about　530　MPa　and　985　MPa,　respectively.　©　2022　by　the　authors.　Licensee　MDPI,　Basel,　Switzerland.
