“…Since the magnetic properties of amorphous nanocrystalline materials are extremely sensitive to the annealing temperature, many studies have been conducted on the magnetic mechanism from the annealing process [13][14][15]. Wang et al [16][17][18][19][20] studied the effects of the annealing rate, annealing temperature, holding time, and annealing atmosphere on the magnetic properties from the perspective of the annealing process. Han et al [21][22][23] studied the effects of the magnetic metal content and alloying elements on the magnetic properties from the perspective of composition.…”

Fe 71 Si 16 B 9 Cu 1 Nb 3 amorphous alloy ribbons were prepared with a single roll polar method. X-ray diffraction analysis of the surface samples was completely amorphous. The thermal stability parameters T x , T p , and T end of amorphous ribbons were measured with a synchronous thermal analyzer under high purity argon gas and analyzed for their crystallization behavior. The heating rate was 10 K min −1 , 15 K min −1 , 20 K min −1 , and 30 K min −1 . The T x and T p of the Fe 71 Si 16 B 9 Cu 1 Nb 3 amorphous alloy increased with an increase in the heating rate, indicating that the crystallization behavior has a kinetic effect. The crystallization activation energy of the amorphous alloy was calculated using the Kissinger and Ozawa equations, respectively. The calculation results of the two methods were consistent. The sample was annealed (761 K, 786 K, 801 K, and 858 K, holding for 300 s) under the protection of high purity argon. The phase transition and microstructure transformation of the amorphous alloy during isothermal crystallization were analyzed by x-ray diffraction. When the alloy was annealed at 801 K, a single α-Fe(Si) solid solution precipitated on the amorphous matrix. Magnetic properties were measured using a vibrating sample magnetometer and observed by transmission electron microscopy. When the alloy was annealed at 786 K and 801 K, the saturation magnetic induction reached 1.22∼1.27 T, coercivity was as low as 5.3∼7.2 A m −1 , and the average grain size was about 10∼20 nm.

Fe-based amorphous and nanocrystalline alloys are widely used in transformers, electronic information, and aerospace applications due to their high saturation flux density (B s ), high permeability, low iron loss, and low coercivity (H c ). This article briefly introduces soft magnetic materials, gives an overview of the classification, preparation methods, soft magnetic properties, and applications of Fe-based amorphous and nanocrystalline alloys, and reviews the effects of elements such as Fe, Co, Ni, Si, B, P, and Nb in the alloys on the properties of Fe-based amorphous and nanocrystalline alloys such as amorphous forming ability, B s and H c . The challenges and development directions of Fe-based amorphous and nanocrystalline alloys in research are pointed out.
