| The paper presents the results of tests carried out on samples of FeCoB-based alloys. The samples were produced by a technique involving the injection of each liquid alloy into a copper water-cooled mould. The investigated materials are characterised by much better properties than their crystalline counterparts with the same chemical composition. It has been shown that the cooling rate has a significant impact on the magnetic properties of the produced alloy. Alteration of the production parameters of FeCoB alloys has a decisive influence on the resulting properties of these alloys. The research has revealed evidence that changes in the structural characteristics are related directly to changes in the magnetic properties. |
