摘要：
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.
