## 3 Results and Discussion  
### Characteristic Quantities  
Initially, the Fe\({}_{1\text{-}x\text{-}y}\)Ni\({}_{x}\)Co\({}_{y}\) alloy, x = 0.32, y = 0.05 (Fe\({}_{63}\)Ni\({}_{32}\)Co\({}_{5}\)) with 13,500 atoms corresponding to 8505 Fe atoms, 4320 Ni atoms, and 675 Co atoms were set at T = 4500 K, P = 0 GPa, for recovery statistics, with 2 \(\times\) 10\({}^{4}\) steps, simulation step time is 1 fs, and heating rate 4 \(\times\) 10\({}^{11}\) K/s (to obtain initial stabilization for the studied material). Characteristic quantities, structure, phase transition, and crystallization are shown in Figure 1.  
The obtained results show that at temperature (T), T = 300 K, the Fe\({}_{63}\)Ni\({}_{32}\)Co\({}_{5}\) alloy has the shape of a cube, composed of 03 metals Fe (green), Ni (violet), Co (black), fairly evenly distributed, arranged in an orderly manner (Figure 1a). In addition, there are structural characteristic quantities such as the structured shape (Figure 1b) composed of 04 structural units: Face-centered cubic (FCC) has a red color, Hexagonal Close-Packed (HCP) is blue, Body-centered cubic (BCC) is black, and Amorphous (Amor) is yellow. The radial distribution function has links Fe-Fe, Fe-Ni, Fe-Co, Ni-Ni, Ni-Co, Co-Co corresponding to the lengths of the links rFe\({}_{\text{Fe-Fe}}\) = rFe\({}_{\text{Fe-Ni}}\) = rFe\({}_{\text{Fe-Co}}\) = rNi\({}_{\text{Ni-Ni}}\) = rNi\({}_{\text{Co-Co}}\) = 2.475 A. The obtained results are completely consistent with previous simulation results (such as with bond lengths Fe-Fe, Ni-Ni, Fe-Ni, where the corresponding value is rFe\({}_{\text{Fe-Fe}}\) = 2.55 A [17; 18; 44; 45; 46] for amorphous Fe; rNi-Ni = 2.45 A [19; 20] for Ni crystallization; and rFe-Ni = 2.47 A [32], 2.48 A [47] with 2-component alloys). Based on the experimental method rFe\(\rm r_{Fe-Fe}=2.62\) A [49] with the neutron method; \(\rm r_{Fe-Fe}=2.57\) A [50] with X-ray method for amorphous Fe; with two component alloys \(\rm r_{Fe-Ni}=2.53\) A [51]. Our computational results are completely consistent with the bond lengths of crystalline metals and have a smaller value for metals in the amorphous state. Currently, there are no studies about the structural characteristics of 3-component alloys. The authors will compare the lengths of the bonds with the bond lengths of the previous 1-component metal or 2-component alloy. Due to the electronic interaction, the lattice constant values of these three-component alloys are approximately equal and in addition, all are ferromagnetic. Moreover, the height g(r) of the radial distribution function (RDF) is g(r)\({}_{\rm Fe-Fe}=8.12\), g(r)\({}_{\rm Fe-Ni}=7.32\), g(r)\({}_{\rm Fe-Co}=8.20\), g(r)\({}_{\rm Ni-Ni}=6.92\), g(r)\({}_{\rm Ni-Co}=7.34\), g(r)\({}_{\rm Co-Co}=6.76\) (Figure 1c). In which, the height g(r) of the radial distribution function (correlation function) is the probability density function of finding the atom in the coordination number circle [66]. Correspondingly, the number of structural units associated with \(\rm Fe_{63 Ni_{32}Co_{5}}\) alloy is 7290 FCC, 4860 HCP, 364 BCC, and 986 Amor (Figure 1d). In addition, at T = 300 K, P = 0 GPa, the size of the alloy (I) corresponds to I = 5.33 nm, the total energy of the system (E\({}_{\rm tot}\)), \(\rm E_{tot}=-58\),263 eV. The specific results for the structure of the \(\rm Fe_{63}Ni_{32}Co_{5}\) alloy, allow us to study the influencing factors in the following sections.
