Data-driven discovery of a universal indicator for metallic glass forming ability

Ming-Xing Li et al.

Summary: The glass forming ability of alloys is closely related to the full-width at half-maximum of the first diffraction peak in the X-ray diffraction pattern, providing guidance for the discovery of bulk metallic glasses. Through experimental and computational methods, it has been revealed that the glass forming ability of an alloy is mainly characterized by its amorphous structure. A strong correlation has been found between high glass forming ability and a large dispersion of structural units in the amorphous structure.

Excellent soft magnetic properties and enhanced glass forming ability of Fe-Si-B-C-Cu nanocrystalline alloys

Jifeng Zhou et al.

Summary: The glass forming ability, thermal stability, and soft magnetic properties of Fe85Si6-xB8Cu1Cx alloys were investigated by substituting C for Si. It was found that the addition of C remarkably enhanced the glass forming ability and improved the temperature interval between crystallization temperatures. Fe85Si4B8Cu1C2 alloy exhibited the best soft magnetic properties with high saturation magnetic flux density and low coercivity, making it suitable for various applications.

Optimization of crystallization, microstructure and soft magnetic properties of (Fe0.83B0.11Si0.02P0.03C0.01)99.5Cu0.5 alloy by rapid annealing

Min Zhao et al.

Summary: A (Fe0.83B0.11Si0.02P0.03C0.01)(99.5)Cu-0.5 glass former was developed based on Fe83B11Si2P3C1 alloy. A new rapid annealing method was used to investigate the effect of temperature and time on the improvement of soft magnetic properties. The results show that the addition of Cu expands the interval between the first and second crystallization temperature. The alloy ribbon annealed by the new method exhibits higher saturation magnetization and lower coercivity compared to other nanocrystalline alloys with similar Fe content.

Heterostructured crystallization mechanism and its effect on enlarging the processing window of Fe-based nanocrystalline alloys

Tao Liu et al.

Summary: A novel strategy of annealing the partially crystallized precursor ribbons via a heterostructured crystallization process was proposed to enlarge the processing window of high saturation magnetization nanocrystalline soft-magnetic alloys. By studying the heterostructured evolution of alloy ribbons with different spinning rates, the gradient nucleation and grain refinement mechanisms were demonstrated. This strategy not only improves the magnetic properties and nanostructure of the alloys, but also allows for greater compositional adjustability and impurity tolerance.

Rapid Annealing Optimizing Magnetic Softness and Thermal Stability of Mn-Substituted Fe-Based Nanocrystalline Alloys

Bojun Zhang et al.

Summary: This study found that Mn-doping and rapid annealing in Fe-based nanocrystalline alloys can lead to superior magnetic softness, high-saturation magnetic induction, and large permeability. This is attributed to the superb nano-structural stability and the formation of regular magnetic domains.

Summary: In this study, the effects of adding different ferromagnetic elements, metallic elements with strong non-metallic properties, and transition metal elements with large atomic radius on the crystallization behavior, magnetic properties, and ductility of Fe85Si0.5B9P4Cu0.5C0.1M0.9 alloys were systematically investigated. Through optimal heat treatments, nanocrystalline alloys exhibited excellent soft magnetic properties but further understanding of the microscopic mechanism of plastic deformation and achieving high toughness in amorphous alloys is crucial.

Prediction of density in amorphous and nanocrystalline soft magnetic alloys: A data mining approach

R. Parsons et al.

Summary: This study reviewed literature to determine the density of amorphous soft magnetic alloys and found it can be accurately described by a regression function. The change in density during amorphization and subsequent nanocrystallization was estimated to be between 0.5% and 3%, depending on the alloy composition. The difference in density between a crystalline precursor ingot and after amorphization by melt spinning was observed to vary between 2% and 3%.

Nanocrystalline Fe83Si4B10P2Cu1 ribbons with improved soft magnetic properties and bendability prepared via rapid annealing of the amorphous precursor

Yang Meng et al.

Summary: This study demonstrated that nanocrystalline Fe83Si4B10P2Cu1 ribbons obtained through rapid annealing have higher crystallinity and finer alpha-Fe nanocrystallites compared to ribbons prepared through conventional annealing, leading to improved magnetic properties and bendability. Rapid annealing at 520 degrees C for 30 s successfully produced Fe83Si4B10P2Cu1 nanocrystalline ribbons with high saturation magnetization, low coercivity, and enhanced bendability suitable for electronic components with complex geometries.

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.
