Nanocrystalline (Fe,Co,Ni)86B14 soft magnetic alloys prepared by ultra-rapid annealing

Z. Li et al.

Summary: This study investigated the glass-forming range, microstructural features, and soft magnetic properties of (Fe(1-x-)yCo(x)Ni(y))(86)B-14 alloys. It was found that Fe-rich compositions have the largest glass-forming range and exhibit nano-scale grains with bcc and fcc structures after ultra-rapid annealing. The coercivity and saturation magnetic polarization of the nanocrystalline alloys are affected by Co and Ni content, with Co addition generally increasing coercivity and saturation magnetic polarization, while Ni addition has the opposite effect.

Improvement of soft magnetic properties of a Fe84Nb7B9 nanocrystalline alloy by synergistic substitution of P and Hf

Tenigeer Li et al.

Summary: A strategy of similar elements synergistic substitution was implemented to enhance the amorphous forming ability, thermal stability, and soft magnetic properties of Fe-Nb-B nanocrystalline alloys. Substitution of B by P improves the amorphous structure, decreases coercivity, and increases saturation magnetic flux density. Subsequent replacement of Nb by Hf increases the thermal stability, refines grain size, and improves structural uniformity, thereby enhancing the soft magnetic properties and enlarging the optimum annealing temperature window.

Formation and crystallization behavior of Fe-based amorphous precursors with pre-existing α-Fe nanoparticles-Structure and magnetic properties of high-Cu-content Fe-Si-B-Cu-Nb nanocrystalline alloys

Yanhui Li et al.

Summary: The structure, crystallization behavior, and magnetic properties of Fe81.3Si4B13Cu1.7 alloy ribbons were studied, as well as the effects of Nb alloying. High-density Cu-clusters and Pre-existing Nano-sized alpha-Fe Particles were found in the amorphous matrix, and the number densities of these clusters were gradually reduced with Nb enrichment. Nb alloying also affected the average size of alpha-Fe grains after annealing, with 4 at.% Nb refining the grains to 8.9 nm. Mechanisms of alpha-Fe nucleation and growth during quenching and annealing were discussed, and a coercivity correlation with alpha-Fe was found, with permeability inversely related to coercivity.

Effect of the substitution of Si for B on thermal stability, magnetic properties and corrosion resistance in novel Fe-rich amorphous soft magnetic alloy

Yanzhou Fan et al.

Summary: Soft magnetic alloy Fe83.3SixB16-xCu0.7 (x = 0, 1, 2, 3 and 4) ribbons were produced by single roller melt spinning method. The addition of appropriate amount of Si improves thermal stability, soft magnetic properties and corrosion resistance. Alloy with x = 1 shows excellent soft magnetic properties and improved corrosion resistance, making it a promising candidate for future applications.

Design of Fe-based nanocrystalline alloys with superior magnetization and manufacturability

Hu Li et al.

Summary: A revolutionary nanostructure design concept was proposed in this study to improve the magnetic properties of Fe-based alloys by preforming dense nuclei and refining nano-structure via transient metalloid-rich interfaces. A novel alloy composition with superior magnetic properties was developed using only 4.6 wt.% light metalloids, showing great potential as a substitute for commercial bulk Si-steels in soft-magnetic applications.
