“…Consequently, 6 the temperature interval between the two distinct exothermic peaks (Tx2-Tx1) increases from 50 ºC to 155 ºC with increasing Co/Ni contents. According to our previous research, the first exothermic peak corresponds to the precipitation of α-Fe(Co,Ni) [18], and therefore the increase of (Tx2-Tx1) will be beneficial to form α-Fe(Co,Ni) clusters.…”

“…The conventional method to cover this shortage is to increase the Fe content [5,6]. High Fe-content alloys like FeSiBPCu [7,8] and FeSiBPCuC [9,10] have been developed one after another. However, the H c of high Fe-content alloys increases rapidly during annealing at a low heating rate due to the rapid crystallization of α-Fe on pre-existing nuclei [11].…”

In this paper, the effect of the replacement of Fe by Nb on the glass forming ability (GFA), the thermal stability and the crystallization behavior of Fe84.5−xSi0.5B10.5P3.5Cu0.7C0.3Nbx (x = 0, 1, 2) alloys were investigated. The results show that the addition of Nb increases the GFA. Increasing Nb content can enhance the first onset crystallization temperature (Tx1), the second onset crystallization temperature (Tx2) and ΔTx (ΔTx = Tx2 − Tx1), which broadens the range of annealing temperatures. The coercivity (Hc) of ribbons decreases with increasing Nb content after annealing at a low heating rate and reach as a minimum of 24.5 A/m when the Nb content is 2 at.%. The process of annealing at a high heating rate distinctly decreases Hc, and all samples present excellent soft magnetic properties. The nanocrystalline alloy exhibits the lowest Hc of 6.4 A/m after annealing at 460 • C for 5 min.

“…The required magnetic properties are usually large saturation magnetization, low coercive field and high magnetic permeability. Fe-based metallic glasses can be characterized by their chemical compositions containing metalloids (B, Si, P), other metals (Co, Ni, Cu, Zr, Hf, Mo, Nb, Al, Ta) and also rare earth elements [1][2][3][4][5][6].…”

The ferromagnetic Fe-based amorphous alloys were studied due to properties for soft magnetic applications. Depending on different Nb addition, the formation of crystalline phases after annealing of amorphous Fe80−xB20Nbx (x = 4, 6, 10) alloys was studied. The crystallization products as well as the phase structure were determined using the Mössbauer spectrometry combined with differential scanning calorimetry and magnetic measurements. The addition of Nb caused a shift of crystallization process towards higher temperatures and induced changes in coercive force and decreased the saturation magnetization. It was found that Nb addition changed the crystallization process from single crystallization for Fe76B20Nb4 alloy to binary crystallization in the Fe74B20Nb6 and Fe70B20Nb10 glasses. The annealing process at the onset crystallization temperature induced complex phase formation including the α-Fe, Fe3B, and Fe2B phases for alloys x = 4, 6.
