A Novel CoFe2NiMn0.3AlCux High-Entropy Alloy with Excellent Magnetic Properties and Good Mechanical Properties

In the present study, we investigate the crystal structure of high-entropy alloys (HEAs) in the form of CoFe2NiMn0.3AlCux (x = 0.25, 0.50, 0.75, and 1.00) and their mechanical and magnetic properties. The CoFe2NiMn0.3AlCux alloys are composed of a mixture of a body-centered cubic (BCC) and a face-centered cubic (FCC) solid solution. The increased amounts of copper (Cu) boost both alloy strength and plastic ductility. The CoFe2NiMn0.3AlCu1.0 HEAs...
