“…For the as-cast sample of Fe 62 Co 9 W 1 Y 8 B 20 made by injection-casting, the size of the Fe 5 Y andαFe crystalline grains was found to be very small. As suggested by many Mössbauer studies of FeCoB [26,33] alloys, there are areas of differing iron concentrations present within the volume of these materials; that is, within the amorphous matrix, some areas are more favorable for the creation of crystalline grains. It can be assumed from the iron-rich amorphous matrix (the low-field component from the Mössbauer spectra) that iron and yttrium were precipitated to create the Fe 5 Y and αFe phases.…”

The paper presents the results of research on the structure and magnetic properties of Fe61+xCo10−xW1Y8B20 alloys (where x = 0, 1 or 2). The alloys were produced using two production methods with similar cooling rates: Injection casting and suction casting. The alloy samples produced were subjected to isothermal annealing at 940 K for 10 min. The structure of the materials was examined using X-ray diffraction. Isothermal annealing has led to the formation of various crystallization products depending on the chemical composition of the alloy and the structure of the alloy in a solidified state. In two cases, the product of crystallization was the hard magnetic phase Y2Fe14B. However, the mechanism of this phase formation was different in both cases. The magnetic properties of alloys were tested using a vibrating sample magnetometer and a Faraday magnetic balance. It is found that the grain crystallite size of the crystalline phases have a decisive influence on the value of the coercive field (especially in the case of hard magnetic phases). It has been shown that privileged areas can already be created during the production process. Their presence determines the crystallization process.

“…Under the condition of rapid solidification, the Niobium‐rich phase in the form of spherical particle is dispersed in the Yttrium‐rich matrix after complete solidification . Such a composite microstructure with in situ crystalline spheres embedded into crystalline alloy matrix is normally formed in various immiscible alloys . The addition of other element, such as Nickel, into Niobium‐Yttrium alloy presents the capability of the formation phase‐separated glass which shows an improved plasticity and the hardness .…”

The rapid solidification experiments have been carried out for the Nb(45‐x)YxNi55 (x = 9, 19, and 27) alloys. The microstructure characterization shows the occurrence of the liquid‐liquid phase separation into the Niobium‐rich and Yttrium‐rich liquids. The Niobium‐rich spherical particles were embedded in the glassy Yttrium‐rich matrix for the alloy Nb36Y9Ni55, while glassy Yttrium‐rich ones were located in the glassy Niobium‐rich matrix for the alloy Nb18Y27Ni55. A structure of hierarchical separation was detected in the as‐quenched alloy Nb26Y19Ni55. The size distribution of the spherical particles in the as‐quenched Nb(45‐x)YxNi55 (x = 9 and 27) alloys ranges from several nanometers to sub micrometer and is close to the Gaussian distribution. The average diameters of the Niobium‐rich particles in the as‐quenched Nb36Y9Ni55 alloy and the Yttrium‐rich particles in the Nb18Y27Ni55 alloy are 0.23 μm and 0.15 μm, respectively. A dual‐glass structure in the as‐quenched Nb18Y27Ni55 alloy ribbon was determined by X‐ray diffraction and transmission electron microscopy.
