Fe81.5Si0.5B4.5P11Cu0.5C2 nanocrystalline alloy with high Fe concentration possesses a finely uniform nanocrystalline structure and numerous α-Fe crystals with a mean grain size of ∼17 nm based on XRD patterns. Such crystals precipitated from the amorphous matrix. Favorable soft magnetic properties, small value of coercivity (Hc) of ∼4.8 A/m, and high magnetic flux density (Bs) of ∼1.53 T can be achieved by slow heat treatment (heating rate of ∼10 °C/min). In this case, one-step annealing at a low heating rate is truly antipodal to Fe–Si–B–P–Cu alloy. We analyzed the nanocrystallized mechanism during annealing with various heating rates in Fe81.5Si0.5B4.5P11Cu0.5C2 alloy, which inevitably simplified the industrial crystallization process by one-step annealing at a low heating rate.
