چکیده	This study offers valuable insight into the effect of the cyclic closed-die forging (CCDF) technique on the electrochemical behavior of cost-effective single face-centered cubic (FCC)-structured Fe50−2xMn30Co10Cr10NixCux (x = 0, 5 at%) high-entropy alloys (HEAs) in a 0.5 M H2SO4 solution. Electrochemical experiments demonstrated that the high strains imposed during CCDF processing, along with the extremely fine grains, significantly improved the electrochemical performance of alloys. Additionally, the Fe50Mn30Co10Cr10 alloy exhibited a lower corrosion current density value due to its more uniform distribution of equiaxed nanograins and the absence of Cu segregation phase. This, in turn, creates better conditions for the formation of passive films with superior protection behavior compared to the Fe40Mn30Co10Cr10Ni5Cu5 alloy. These findings open new avenues for the exploration of cost-effective nanostructured HEAs in electrochemical applications.
