摘要

In this study, the effect of grain refinement on the electrochemical behavior of the cost-effective Fe30Ni25Cr25Mo10Al10 high-entropy alloy heavily deformed through cyclic closed-die forging (CCDF) was investigated in a 0.5 M H2SO4 solution. The as-homogenized Fe30Ni25Cr25Mo10Al10 alloy exhibited a two-phase microstructure of the [CrMoFe]-rich dendrites with dual size distributed in a nearly homogenous face-centered cubic (FCC) high-entropy matrix. It was observed that the CCDF technique was a promising process for exhibiting an equiaxed morphology in this alloy, accompanied by a high fraction of nanograin regions, and the grain size distribution was relatively uniform. Additionally, the electrochemical measurements confirmed that the electrochemical behavior of the Fe30Ni25Cr25Mo10Al10 alloy was improved by implementing the CCDF technique due to the improved surface conditions promoting the formation of oxide films through higher homogeneity facilitation.
