This paper is related to the evaluation of the possibility of using ferroalloys for the production of conventional (CMGs) and bulk metallic glasses (BMGs) as well as determining their magnetic properties. The structure and magnetic properties of Fe-Co-based CMGs and BMGs prepared from ferroalloys and pure elements, were studied. The CMGs and BMGs were in the form of ribbons and rods, respectively. The thickness of the ribbons were 0.07, 0.12, and 0.27 mm and the diameters of the rods were 1.5 and 2.5 mm. The investigations of the structure of the test specimens were carried out using the X-ray diffraction (XRD) method and electron microscopy methods (HRTEM-high-resolution transmission electron microscope, SEM-scanning electron microscope). The relationship between the structure and magnetic properties of the FeCoBSi₅Nb₄ and FeCoBSi₅Nb₄Cu CMGs and BMGs was determined. The possibility of using new materials, i.e., CMGs and BMGs, prepared on the basis of ferroalloys, lies in the scope of the presently conducted research and allows us to obtain the utility properties, while avoiding high costs associated with the purchase of raw materials.
本文涉及评估使用铁合金生产传统金属玻璃复合材料（CMGs）和大块金属玻璃（BMGs）的可能性，以及测定它们的磁性。研究了由铁合金和纯元素制备的铁钴基CMGs和BMGs的结构与磁性。CMGs和BMGs分别呈带状和棒状。带材的厚度分别为0.07、0.12和0.27毫米，棒材的直径分别为1.5和2.5毫米。使用X射线衍射（XRD）方法和电子显微镜方法（HRTEM - 高分辨率透射电子显微镜、SEM - 扫描电子显微镜）对测试样品的结构进行了研究。确定了FeCoBSi₅Nb₄和FeCoBSi₅Nb₄Cu CMGs和BMGs的结构与磁性之间的关系。基于铁合金制备的新型材料，即CMGs和BMGs的使用可能性，在于当前所进行的研究范围内，并且使我们能够获得实用性能，同时避免与购买原材料相关的高成本。
