The paper presents the study of the influence of different ferromagnetic powders on magnetic properties of polymer-matrix soft magnetic composites. Samples were prepared from pure Fe and Permalloy powders with the same amount of resin and by the same technological process. The coercivity, the real part of complex permeability, saturation magnetic polarization, hysteresis loops and total energy losses and their components were investigated. It was found that the coercivity, DC losses, classical losses, excess losses and thus the total energy losses of composites depended on intrinsic magnetic properties and/or on the size and shape of ferromagnetic powder particles, while the permeability of composites was affected predominantly by inner demagnetizing fields due to the insulation. The numbers of moving domain walls involved in magnetization reversal were analyzed in connection with the magnetic properties.

Influence of the Ferromagnetic Component on the Magnetic Properties of Polymer-Matrix Soft Magnetic Composites

<abstract xmlns="http://www.w3.org/1999/xhtml">

Soft magnetic composite materials consisting of FeSi powder and polypropylene were prepared by the injection molding method, with different polypropylene contents of 25, 30 and 35 vol. %. The magnetic and electrical properties as well as the structure of the composites were investigated. The samples exhibited very low porosity, high electrical resistivity, relatively low coercivity, sufficient saturation magnetic flux density and permeability, and high resonant frequency. FeSi particles were found to be well insulated from each other and homogeneously dispersed in the polymer matrix of the composite. The observed isotropic structure was confirmed by the fitting of the experimental dependence with the analytical expression of the reversible relative permeability vs. magnetic flux density.

Iron Based Soft Magnetic Composite Material Prepared By Injection Molding

<abstract xmlns="http://www.w3.org/1999/xhtml">

The results of the investigation of the structure, phase composition, and properties of the alloy sintered from a mixture of iron (65 %) and high-carbon ferrochrome (35 %) powders are presented in the article. It was shown that sintering of the consolidated specimens results in a substantially heterogeneous structure consisting of two predominant phases: austenitic phase and double ferrochrome carbide. A mechanism is proposed for the dissolution of ferrochrome particles in the iron matrix as follows: M7C3 → M3C (1000÷1150 ºС) → M7C3 (1200÷1250 ºС).
