Nanocrystalline Fe88−2xCoxNixZr7B4Cu1 alloys: Soft magnets for vehicle electrification technologies (invited)

We report on the effect of substituting Co and Ni for Fe on the crystallization behavior, crystal structure, and magnetic properties of Fe88−2xCoxNixZr7B4Cu1 (x = 0–22.00). The magnetization generally decreases and the coercivity increases with increasing x, whereas the Curie temperature of the amor...

description We report on the effect of substituting Co and Ni for Fe on the crystallization behavior, crystal structure, and magnetic properties of Fe88−2xCoxNixZr7B4Cu1 (x = 0–22.00). The magnetization generally decreases and the coercivity increases with increasing x, whereas the Curie temperature of the amorphous phase increases significantly (from 73 °C at x = 0 to 570 °C at x = 22.00). There is thus an optimum composition near x = 5.50 exhibiting excellent soft magnetic properties at 300–500 °C. The higher magnetization and Curie temperature as compared with Fe-based alloys, and smaller Co content as compared with (Fe,Co)-based alloys, make this alloy attractive as an affordable high-temperature soft magnetic material.
