Novel Co_(35)Cr_5Fe_(20)Ni_(20)Ti_(20) high entropy alloy for high magnetization and low coercivity

摘要

A novel Co35Cr5Fe20Ni20Ti20 high entropy alloy (HEA) is synthesized through mechanical alloying (MA). The synthesized HEA is comprised of mixture of FCC and BCC phases and exhibits soft magnetic properties with M-s = 46 emu/g and H-c = 15 Oe. After annealing at 200 degrees C, the value of Ms is increased approximately two times and coercivity remains the same to as synthesized HEA. The found value of Ms (81 emu/g) is the highest value of Ms for the CoCrFeNiTi-based HEA, reported so far.
