“…Iron and silicon are mostly used as common alloying ingredient in aluminium alloys to enhance the mechanical strength [1,2]. Al-Fe-Si system possesses high oxidation resistance and hence are mainly used for food packaging, magnetic materials for transformers, lithographic printing sheets, capacitors [2][3][4] and building materials [5]. The addition of iron and vanadium to the Al-Si alloy enhances the wear resistance significantly with respect to the conventional Al-Si alloy [6].…”

Temperature-dependent interaction parameters for excess free energies of mixing of sub-binary systems of Al-Fe-Si ternary liquid alloys were optimised using the experiment data in the frame of Redlich-Kister (R-K) polynomials. These optimised parameters were then used to compute the partial excess free energy of sub-binary and ternary liquid alloys. The surface tension and surface concentration of sub-binary and the ternary liquid alloys were computed using Butler equation. The temperature dependent coefficients of R-K polynomials for excess surface tensions of the sub-binary systems were optimised which were then used to estimate the surface tension of ternary alloy using Chou, Kohler and Toop modelling equations at temperatures 1773, 1873, 1973 and 2073 K. The surface tension of the ternary alloy obtained using aforementioned models were found to be in good agreement from Fe and Al corners but some deviations were observed from Si corner.

Aluminum-Iron-Silicon (Al-Fe-Si) alloys are extremely applied in many specific industries, such as aerospace and automobiles. Their atomic concentration influences the mechanical behavior of the investigated τ4-Al3Fe2Si and τ12-Al3FeSi2 phases. The uniaxial-tensile deformation is used to compare their structural evolution under the same conditions.Atomic displacement and mechanical behavior have an interest in the elastic and plastic areas. Stress-Strain responses and Radial Distribution Function (RDF) are required. Further, atomic simulations using molecular dynamics demonstrate the change occurs. Its process is carried out at a strain rate of 21×1010 s-1 using the NPT (isothermal-isobaric) with roughly 20 700 atoms at a pressure of 105 Pa. Furthermore, using a Nosée Hoover thermostat at the temperature of 300 k is decisive.The Modified Embedded Atoms Method (MEAM) is the applied potential between Al, Fe, and Si atoms. The elastic modulus and single pair atomic correlation before and after straining are increased by this method. The atomic correlations are shown in short- and long-range order and the τ12-Al3Fe2Si phase illustrates stronger properties compared to τ4-Al3Fe2Si phase. Our results underscore an important variation associated with the change of iron and silicon concentration. More specifics are covered in the selection paper.
