摘要

Rapidly quenched systems based on Fe-Co-B-Si with addition of Cu and P are very interesting for their excellent soft magnetic and mechanical properties. These physical properties are given by the structure formed from amorphous state after controlled annealing. Selected amorphous systems of this type have been prepared by planar flow casting in form of thin ribbons. Materials after heat treatment exhibit fine-grains of bcc-Fe in amorphous matrix and subsequently borides. The influence of the substitution of Fe for Co, the substitution of B for Si and the additions of P and Cu on structure in nanocrystalline state was investigated. Transformations were detected using the methods of differential scanning calorimetry (DSC). X-ray diffraction (XRD), transmission electron microscopy (TEM) and electron diffraction (ED) analyses on samples heat-treated at selected temperatures were performed to obtain information about the structure, morphology, size and distribution of transformed grains in amorphous matrix of the investigated system.
