Mechanical properties and the structure of magnetic composite materials

Purpose: The purpose of the paper is to present the material and technological solution which makes possible obtaining soft and hard magnetic composite materials: nanocrystalline material - polymer. Design/methodology/approach: The main base of the paper is to compare the structure and mechanical properties of chosen magnetic composite materials with polymer matrix reinforced with Nd-Fe-B or FINEMET particles manufactured by one-sided uniaxal pressing. The complex relationships among the manufacturing technology of these materials, their microstructure, as well as their mechanical and physical properties were evaluated. Findings: Modern magnetic materials have optimum technology of production with properties that allow for miniaturizing, simplification and lowering the costs of devices Practical implications: The manufacturing of composite materials greatly expands the applicable possibilities of nanocrystalline powders of magnetically hard and soft materials however further examination obtain improved properties of magnetic composite materials. The investigations of constructing of new machines and devices with these materials elements are still needed. Originality/value: The paper shows the base of the material and technological solution which make possible obtaining magnetic composite materials and their mechanical properties which are not commonly presented in other papers.
