Abstract
New ferromagnetic (Fe1/3Co1/3Ni1/3)80(P1/2B1/2)20 high entropy bulk metallic glass (HE-BMG) with the maximum diameter of 2 mm has been prepared by combining fluxing treatment and J-quenching technique. The present HE-BMG exhibits excellent soft magnetic properties with a saturation magnetization of 0.90 T, low coercivity of 1.5 A/m, high permeability of 10172 @ 1 kHz and low hysteresis loss of 21 kJ/mol @ 50 Hz (for the annealed glassy ribbon), and mechanical properties with a compressive yield strength of 3000 MPa and large plastic strain of 4%. The combination of superior glass-forming ability, excellent magnetic and mechanical properties makes the present HE-BMG a future promising application as advanced structural and functional materials.
