The equiatomic FeCoNiCuMn high entropy alloy (HEA) was prepared by vacuum arc-melting under argon atmosphere, andthe as-cast alloy was subsequently annealed at 850 °C and 1000 °C for 2 and 12 h. The annealing effects on the microstructure,magnetic, electrical, and mechanical properties were investigated. Based on the microstructural analysis, three majorphases were found in different conditions; (Fe, Co)-rich phase, Cu-rich phase, and homogenized solid solution phase. ThisHEA showed excellent soft magnetic properties (proper saturation magnetization (40 emu/g), low coercivity (7 Oe) and lowmagnetic remanence ratio (0.03)) and high electrical resistivity (287 μΩ.cm) with proper strength and good ductility (41%).
All these properties together make FeCoNiCuMn HEA better than that of the most reported soft magnet HEAs, and it canbe used as a soft magnetic material in the future.
