“…This raises the thermodynamic stability of Al 9 Fe 2 phase in Co containing Al alloys [17]. It was also reported that Co can diffuse to y-Al(Fe)Si phase and bring about an increase in its size [18]. Therefore we can presume that Co can diffuse Fe-bearing intermetallic phases and cause an increase in their size as it can be seen in Fig.…”

“…The research of Jiang and Liu [9] showed that the addition of Co can promote the stability of intermetallic compound -AlFe (Si) thus properties improved. Crepeau concluded that [10] like the common neutralizer Mn for ␤-Al 5 FeSi phases, the addition of Co could change the Fe-containing phases to spheroid.…”

“…At the same time, there is information that the α phase has very high Vickers hardness values, including in comparison with the β phase. An effective way to suppress the α↔β transformation is also doping with transition metals such as Cr, Mn, Cu, etc., accelerated cooling and exposure to deformation [ [12], [13], [14], [15], [16], [17], [18], [19], [20]].…”

Increasing interest in intermetallic phases of the Al-Fe-Si system is associated with their high specific strength, corrosion and wear resistance, as well as the low cost of their production. To exhibit the most successful combination of properties, it is necessary to impart a specific compact morphology to the precipitated intermetallic phases. It is important to create an alloy with a composition capable of accepting plastic deformation. The purpose of the work is to develop the composition of an Al-Fe-Si system alloy capable of withstanding plastic deformation and determining the corresponding deformation interval. Based on computer modeling, an alloy composition capable of accepting plastic deformation was developed and the corresponding deformation interval was determined. The simulation was carried out in the ThermoCalc software package, TCAL8 database. It has been revealed that alloys with a high content of both silicon and iron are not characterized by the formation of a single-phase region, however, with a certain combination of alloy components, it is possible to achieve a quasi-single-phase structure, when the content of one phase is observed to be more than 90%. The solidus temperatures for different alloy compositions and the boundary conditions for the existence of phases have been determined. The α phase is present in the system from a temperature of 770°C up to a temperature of 446°C. In composition, it is found in the range from 5 to 35% iron with an amount of silicon of 10% and from 0 to 15% silicon with an iron content of 30%. The maximum amount of α phase was obtained for the Al60-65 alloy; Fe30-32; and Si5-10%, deformation temperature range is 600-450°C. Deformation in this region will ensure processing in a quasi-single-phase region without melting.
