Advances in Fe-based amorphous/nanocrystalline alloys

Journal of Applied Physics, 2022
Fe-based amorphous/nanocrystalline alloys exhibit excellent soft magnetic properties, including high saturation magnetic flux density (Bs), high permeability, low coercivity (Hc), and low magnetostriction. They are utilized in distribution transformers, transformers, reactors, and other devices.

Ductile Fe-based amorphous alloy

Materials Science and Engineering: A, 2012
Abstract Experiments demonstrated that the addition of a minute amount of V to Fe 52 Co (20− x ) B 20 Si 4 Nb 4 V x amorphous alloy induces atomic-scale phase separation, which dramatically enhances the plasticity. Especially, Fe 52 Co 17.5 B 20 Si 4 Nb 4 V 2.5 amorphous alloy exhibited a strength of 4.7 GPa and a fracture strain of 8.0%, which ...

Crystallization of Fe-based amorphous alloys

Journal of Non-Crystalline Solids, 1999
An Fe 73.5 Si 15.5 B 7 Nb 3 Cu 1 alloy with a crystalline grain structure is a soft magnetic material since it has good values of permeability while maintaining a saturation magnetization. Thermal annealing of an amorphous melt spun alloy in the temperature range 480-510°C produces a crystalline dispersion of Fe(Si) particles with diameter of the ...

Magnetization in amorphous Ni-Fe-Based alloys

Physica B+C, 1977
Abstract We report on magnetic measurements on amorphous ( Fe x Ni 1− x ) 80 P 10 B 10 alloys with 0 ⩽ x ⩽ 0.5. The amorphous Ni-rich alloys are characterized as weak itinerant ferromagnets. The curvature of the Arrott plots are used for discussing the appearance of an inhomogeneous magnetization.

Microstructure and properties of laser clad Fe-based amorphous alloy coatings containing Nb powder

Journal of Non-Crystalline Solids, 2020
Fe-Cr-Mo-Co-C-B-Nb coatings with the Nb mass fractions of 0, 2, 4 and 6% were prepared on 45 steel by laser cladding. The surface and microstructural evolution, chemical compositions, phases and thermal behavior of the obtained coatings were analyzed ...
