This study presents a comprehensive investigation of the effect of plastic deformation on the microstructure, mechanical, tribological, and corrosion properties of an iron-containing alloy produced by the electroslag remelting (ESR) process. The study focused on two states of the material: as-cast after ESR and deformed after subsequent rolling (ESR-R). Using X-ray fluorescence and X-ray diffraction analysis, as well as electron microscopy, the characteristics of the alloy’s phase composition and microstructure were determined. It was shown that plastic deformation leads to grain refinement, an increase in defect density, and the formation of secondary phases. A significant increase in the microhardness and wear resistance of the material after rolling was observed, accompanied by a decrease in the coefficient of friction. At the same time, an incяrease in corrosion current density and corrosion rate was observed, despite a shift of the corrosion potential toward a more positive region. The results obtained indicate the complex nature of the effect of plastic deformation on the alloy’s service properties and the need to account for the material’s structural state during its application.
