Fe83.5B15Cu1.5Cax (x= 0.04, 0.07, 0.1 and 0.13) alloy ribbons were fabricated by melt spinning. The effects of Ca addition on electrical resistivity and soft magnetic properties were investigated. The results show that with increasing Ca content from 0.04 to 0.13 the electrical resistivity monotonously increases from 0.51 μΩ·m to 0.99 μΩ·m while the core loss reduced by 39% and 28% at 10 kHz and 20kHz under an applied magnetic field of 200 mT, respectively. After annealing at 420°C for 10min, sample with x=0.13 obtains the peak saturation induction density (Bs) of 1.82 T and coercive force (Hc) of 18 A/m. Especially, the core loss of sample x=0.13 decreased by 13% and 34% than that of x= 0.04 at 200 kHz under an applied magnetic field of 25 mT and 50 mT respectively. Therefore, the soft magnetic properties and core loss can be tuned by addition of Ca in Fe-B-Cu alloy ribbons.

Abstract The glass-forming ability (GFA), nanocrystallisation, electrical resistivity and soft magnetic properties of (Fe1-xCox)79Nb3B18 (x = 0, 0.15, 0.3, 0.45, 0.6, 0.75) glassy alloys were investigated. We found that the substitution of Fe by Co is beneficial for improving the GFA. As-spun (Fe0.55Co0.45)79Nb3B18 glassy alloys show the best GFA, along with excellent soft magnetic properties in the supercooled liquid region, with a saturation magnetisation and coercivity of 140 A · m2 · kg-1 and 19.9 A · m-1, respectively, at 60 K. With increasing Co content, the electrical resistivity initially decreases rapidly, and then fluctuates around approximately 70 ± 4 μΩ cm. With increasing the annealing temperature, the saturation magnetisation improves initially, but then decreases for the (Fe0.4Co0.6)79Nb3B18 alloy, and the coercivity does not significantly improve. These newly developed FeCoNbB multicomponent alloys exhibit appreciable GFA, good magnetic properties and low material cost, and they can serve as a promising soft magnetic material for use in industrial applications.

Bulk Nanocrystalline

Bulk nanocrystalline body-centered cubic- (bcc) (Fe,Co) alloy with high saturated magnetization and good soft magnetic properties was synthesized by the simple process of casting and annealing for the glass-type Fe62.8Co10B13.5Si10Nb3Cu0.7 alloy. It crystallizes through two exothermic reactions. The cylindrical glassy rod with the diameter of 1.5 mm was produced by copper mold casting. The subsequent annealing at the temperature higher than that of the first exothermic peak causes the formation of bcc-(Fe,Co) nanocrystalline with particle sizes between 10 and 15 nm. The bcc-(Fe,Co) alloy rods exhibit good soft magnetic properties of 1.35 T for saturation magnetization and 5 A/m for coercive force.
