Abstract
The high pressure torsion (HPT) process was used to process the FeNiCoMoV high-entropy alloy. The open-circuit potential test, the potentiostatic polarization curve test and the electrochemical impedance spectroscopy were used to study the effect of corrosion behavior of FeNiCoMoV High Entropy Alloy in 1M NaOH Solution. The results show that the grain refinement of FeNiCoMoV alloy is significant after 6 cycles of high pressure torsion, the phase structure has not changed and the electrochemical impedance of HPT has a significant increase in 1M NaOH solution. The potential is 11.97% higher than the initial state, the corrosion current density is 93.77% lower than the initial state, and the corrosion resistance is improved obviously.
