“…However, it decreased to 3.1 A/m at the 50 wt.% Fe ratio. These coercivity values are well below the studies in the literature [32,47]. Because it is known that annealing process applied to the soft magnetic materials increases the coercivity values [32,47].…”

“…This situation can be explained by the following mechanism: Based on the energy band theory, magnetic moment of the Fe atom is 2.2 µB, and the magnetic moment of the Ni atom is 0.6 µB. Hence, it is thought that replacement of the Ni atom by the Fe atom in the alloy composition will increase the saturation magnetization value of the alloy [32,45,46]. From the inset hysteresis curve in Fig.…”

“…On the other hand, another important issue is that the ribbons are amorphous throughout their thickness. Accordingly, whether the structure can be completely or partially amorphous depends on several parameters such as the cooling rate of the molten alloy and distance of nozzle to the copper disc [32]. For example, it has been demonstrated by many researchers that the structure is completely amorphous on the surface of the ribbon in contact with the copper disc, but a certain part of its outer surface crystallizes [24,29,31].…”

Alloys of FeNiSiB soft magnetic materials containing variable Fe and Ni contents (wt.%) have been produced by melt spinning method, a kind of rapid solidification technique. The magnetic and structural properties of FeNiSiB alloys with soft magnetic properties were investigated by increasing the Fe ratio. X-ray diffraction analysis and SEM images shows that the produced alloy ribbons generally have an amorphous structure, together with also partially nanocrystalline regions. It was observed that the structure became much more amorphous together with increasing Fe content in the composition. Among the alloy ribbons, the highest saturation magnetization was obtained as 0.6 emu/g in the specimen with 50 wt.% Fe. In addition, the highest Curie temperature was observed in the sample containing 46 wt.% Fe.

“…The results obtained for the Fe 79 B 20Àx M x Cu 1 (where x = 0 or 4; M = Ti, Mo, Mn) alloys presented in Table II are comparable to the results reported by other authors. [84][85][86] The addition of Ti, Mo and Mn to Fe 79 B 20 Cu 1 alloy leads to an increase of amorphous matrix and a decrease in the crystalline phase. Therefore, the doped materials show lower HV IT , E IT , and W elast /W total for both bright and dark regions, respectively, compared to the Fe 79 B 20 Cu 1 alloy.…”

The influence of alloying additions on the microstructure, mechanical, and magnetic properties of bulk Fe79B20Cu1, Fe79B16Ti4Cu1, Fe79B16Mo4Cu1 and Fe79B16Mn4Cu1 (at. pct) alloys was investigated. Nanocrystalline samples in the form of 3 mm rods were prepared directly by suction casting without additional heat treatment. Mössbauer spectroscopy, transmission electron microscopy and scanning electron microscopy studies confirmed that the investigated alloys consist α-Fe and Fe2B nanograins embedded in an amorphous matrix. The addition of alloying elements, such as Ti, Mo and Mn to Fe79B20Cu1 alloy increases the amount of amorphous phase and decreases the presence of Fe2B phase in all examined alloys. The mechanical properties of the samples, such as hardness, elastic modulus, and elastic energy ratio, were analysed by an instrumented indentation technique performed on a 12 × 12 nanoindentation grid. These tests allowed to characterise the mechanical properties of the regions observed in the same material. For the Fe79B20Cu1 alloy, the hardness of 1508 and 1999 HV, as well as Young’s modulus of 287 and 308 GPa, were estimated for the amorphous- and nanocrystalline-rich phase, respectively. The addition of Ti, Mo, and Mn atoms leads to a decrease in both hardness and elastic modulus for all regions in the investigated samples. Investigations of thermomagnetic characteristics show the soft magnetic properties of the studied materials. More detailed studies of magnetisation versus magnetic field curves for the Fe79B20−xMxCu1 (where x = 0 or 4; M = Ti, Mo, Mn) alloy, recorded in a wide range of temperatures, followed by the law of approach to magnetic saturation revealed the relationship between microstructure and magneto-mechanical properties.

“…In addition, nanocrystalline alloys with 2.5-10% Ni exhibit less brittleness compared to that without Ni due to grain refinement and those with 15-20% Ni become less brittle due to reduction of a-ðFe, NiÞvolume fraction. [111,112] In fact, the aforementioned process increases ductilitysimilar to its effect in normal steel, meaning that Ni substitution increases the number of metalmetal bonds with proper mobility, which links the clusters together, resulting in increasing the compressive flexibility in the bulk amorphous. Further, an increase in the amount of Ni decreases the T g and T x .…”

Fe‐based amorphous alloy coatings (Fe‐AACs) have exhibited appropriate corrosion and wear resistance and improve the performance of material surfaces. This study summarizes the advances related to Fe‐based amorphous alloys pertaining to their chemical compositions and manufacturing processes and their associated effect on the amorphous structure, microstructure and properties. In particular, Fe‐based amorphous alloy coatings produced by laser cladding are investigated in order to study the effect of amorphous structure, partial crystallization, and composition on the microstructure, hardness, corrosion and wear resistance of these coatings. In addition, the effect of laser parameters (power and scanning speed) on the geometric and metallurgical characteristics of produced amorphous coatings are also covered.This article is protected by copyright.
