“…4(a) and the emergence of split peaks at about 33 T corresponding to bcc Fe in Fig. 4(b) characterize the microstructure with nanograins embedded in the residual amorphous matrix 31 . As reported previously 32 , crystal phases in FeSi alloys (<10 at.% Si) prefer to form bcc Fe structure during the crystallization where the central Fe atom has 6~8 nearest-neighbor Fe atoms with Si atoms occupying at the residual sites.…”

In this work, an attempt has been made to reveal critical factors dominating the crystallization and soft magnetic properties of Fe81SixB10P8−xCu1 (x = 0, 2, 4, 6 and 8) alloys. Both melt spun and annealed alloys are characterized by differential scanning calorimetry, X-ray diffractometry, Mössbauer spectroscopy, transmission electron microscopy, positron annihilation lifetime spectroscopy and magnetometry. The changes in magnetic interaction between Fe atoms and chemical homogeneity can well explain the variation of magnetic properties of Fe81SixB10P8−xCu1 amorphous alloys. The density of nucleation sites in the amorphous precursors decreases in the substitution of P by Si. Meanwhile, the precipitated nanograins gradually coarsen, but the inhibiting effect of P on grain growth diminishes causing the increase of the crystallinity. Moreover, various site occupancies of Si are observed in the nanocrystallites and the Si occupancy in bcc Fe decreases the average magnetic moment of nanograins. Without sacrificing amorphous forming ability, we can obtain FeSiBPCu nanocrystalline alloy with excellent soft magnetic properties by optimizing the content of Si and P in the amorphous precursors.

“…As the content of C increases from 0 at% to 4 at%, the B s of the cast thin ribbon increased from 1.62 to 1.72 T and the B s of the annealed nanocrystalline alloy thin ribbon rose from 1.78 to 1.86 T. To sum up, replacing Si with a small amount of C can improve B s and the amorphous forming ability of Fe-based amorphous nanocrystalline alloys. [60] According to the confusion principle of amorphous alloy design, the more the elements in the alloy, the better is the amorphous forming ability of the alloy. In 2021, Shi studied the effects of nonmetallic elements B, C, Si, and P on amorphous alloys of Fe 83-85 (B, C, Si) 14-16 P 1 , as shown in Figure 7.…”

Fe-based amorphous and nanocrystalline alloys are widely used in transformers, electronic information, and aerospace applications due to their high saturation flux density (B s ), high permeability, low iron loss, and low coercivity (H c ). This article briefly introduces soft magnetic materials, gives an overview of the classification, preparation methods, soft magnetic properties, and applications of Fe-based amorphous and nanocrystalline alloys, and reviews the effects of elements such as Fe, Co, Ni, Si, B, P, and Nb in the alloys on the properties of Fe-based amorphous and nanocrystalline alloys such as amorphous forming ability, B s and H c . The challenges and development directions of Fe-based amorphous and nanocrystalline alloys in research are pointed out.

“…The duration of the annealing process affects the size and number of the created crystalline grains. The nanocrystalline alloys, resulting from appropriate thermal treatment, are characterized by good soft magnetic properties [4,27]. The amorphous materials with soft magnetic properties are based on iron, cobalt, or nickel.…”

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.
