Purpose: The thermal and magnetic properties of Fe-based bulk amorphous materials in as-cast state in the form of rods and rings were studied. Design/methodology/approach: The studies were performed on Fe72B20Si4Nb4 metallic glass in the form of rods and rings. The amorphous structure of tested samples was examined by X-ray diffraction (XRD) and scanning electron microscopy (SEM) methods. The thermal stability of the glassy samples was measured using differential scanning calorimetry (DSC). The soft magnetic properties examination of tested material contained coercive force and magnetic permeability relaxation measurements. The crystallization temperature (Tp), supercooled liquid region (ΔTx), coercive force (Hc) and magnetic permeability relaxation (Δμ/μ) versus sample thickness of studied glassy samples were also examined. Findings: The X-ray diffraction and calorimetric investigations revealed that the studied Fe72B20Si4Nb4 bulk metallic glasses were amorphous. However, the differences of glass transition temperature and crystallization temperature between samples with selected thickness are probably caused by different amorphous structures. The changing of glass-forming ability and magnetic properties obtained for samples with different shape and thickness is a result of the non-homogenous amorphous structure of tested metallic glasses. The different states of amorphous phase could be caused by the free volume concentrations formed by different cooling rates in casting process. Practical implications: The soft magnetic properties of studied metallic glasses can be formed by different sample thickness which are strictly linked with different states of amorphous structure. Originality/value: The applied methods of materials investigations are suitable to determine the changes of structure and selected properties of studied samples cast in different forms and dimensions, especially in aspect of the soft magnetic properties improvement.
