The change in the structure of the melt, caused by the action of current, leads to a change in the nature of phase transformations during crystallization, the formation of eutectics, which contains a branched $\alpha$-(Fe, Mn, Cu)$_3$Si$_2$Al$_{15}$ intermetallic compound instead of the iron-containing needle-like $\beta$-FeSiAl$_5$ phase. The dependence of the morphology of the iron-containing phases on the parameters of treatment with electric current and their relationship with mechanical properties are established. The most effective modes are determined. They provide an increase in the strength and ductility of the АK5M2 alloy up... to the level of its analogues smelted from primary metals.
