Abstract

Fe-Si-B-P-Cu-C amorphous alloys with high amorphous forming ability and saturation magnetic induction were developed by optimizing B and P concentrations alongside Ni doping. Gas-atomized Fe_80.5Si_0.5B_10.5P₅Cu_0.5C₂Ni₁ powders exhibited full amorphous structure, achieving a high saturation magnetic induction of 180 emu/g after annealing at 420 °C. The annealed powders demonstrated excellent soft magnetic properties, including high permeability and low core loss. Phosphoric acid passivation further reduced core loss by 26 % while retaining a high saturation magnetic induction of 176.8 emu/g. These properties make the alloy a promising candidate for high-power-density and miniaturized magnetic applications.

高磁感应强度铁基纳米晶合金的制备及其磁性能

在Ni掺杂的同时，通过优化B、P浓度，制备出具有高非晶态形成能力和饱和磁感应强度的Fe-Si-B-P-Cu-C非晶态合金。气雾化fe80.5 si0.5 b10.5 p5cu0.5 5c2ni1粉末呈全非晶结构，420℃退火后饱和磁感应强度达到180 emu/g。退火后的粉末具有优良的软磁性能，包括高磁导率和低磁芯损耗。磷酸钝化进一步降低了26%的磁芯损耗，同时保持了176.8 emu/g的高饱和磁感应强度。这些特性使该合金成为高功率密度和小型化磁性应用的有希望的候选者。

期刊介绍： The aim of Advanced Powder Technology is to meet the demand for an international journal that integrates all aspects of science and technology research on powder and particulate materials. The journal fulfills this purpose by publishing original research papers, rapid communications, reviews, and translated articles by prominent researchers worldwide. The editorial work of Advanced Powder Technology, which was founded as the International Journal of the Society of Powder Technology, Japan, is now shared by distinguished board members, who operate in a unique framework designed to respond to the increasing global demand for articles on not only powder and particles, but also on various materials produced from them. Advanced Powder Technology covers various areas, but a discussion of powder and particles is required in articles. Topics include: Production of powder and particulate materials in gases and liquids(nanoparticles, fine ceramics, pharmaceuticals, novel functional materials, etc.); Aerosol and colloidal processing; Powder and particle characterization; Dynamics and phenomena; Calculation and simulation (CFD, DEM, Monte Carlo method, population balance, etc.); Measurement and control of powder processes; Particle modification; Comminution; Powder handling and operations (storage, transport, granulation, separation, fluidization, etc.)
