Soft magnetic high entropy alloys (HEAs) have great potential to be used as industrial material because of their good magnetic properties and balanced mechanical, electrical, and corrosion resistance properties. To further optimize high saturation magnetization (Ms) along with other functional properties, it is critical to understand the effect of Mn, Cu, and Al on the magnetic properties and phase evolution of FeCoNi-based magnetic HEAs. In the present study, a combinatorial approach is adopted to optimize the magnetic properties of Co35 Fe10Ni30Ti20M5 (M = Mn, Cu, and Al) HEA through the variation of a single alloying element and its effects on the phase evolution, microstructure, and magnetic properties. Co35Fe10Ni30Ti20Mn5, Co35Fe10Ni30Ti20Cu5, and Co35 Fe10Ni30Ti20Al5 high entropy alloys were synthesized through mechanical alloying, and the as-synthesized HEAs were comprised of fcc and bcc solid solution phases. The as-synthesized Co35Fe10Ni30Ti20Mn5, Co35Fe10Ni30Ti20Cu5, and Co35Fe10Ni30Ti20Al5 HEAs have the value of saturation magnetization (Ms)- 81, 85 & 79 emu/g and coercivity (Hc)- 18, 28 & 27 Oe respectively. The phase stability of the developed alloys was also investigated through vacuum annealing at 700°C for 2 h duration. After vacuum annealing, both the Ms and Hc increased to 90 emu/g & 37 Oe, 105 emu/g & 43 Oe, and 104 emu/g & 46 Oe, respectively, for Mn, Cu, and Al – containing Co35Fe10Ni30Ti20M5 (M = Mn, Cu, and Al) HEAs. The present study provides a detailed insight into how the variation of a single alloying element and the annealing temperature significantly affect the magnetic properties of CoFeNiTi-based HEA.
