摘要：

The effect of microstructure on the corrosion behavior and film properties of strengthened AlCoCrFeNi2.1 eutectic high-entropy alloy (EHEA) was investigated. Annealing of the 80% cold-rolled AlCoCrFeNi2.1 EHEA at 650-1200 degrees C effectively improved the stable passive region to 930 mV, and decreased the passive current density by 25% to 3.5 mu A/cm2 compared with the cast alloy in 0.1 M H2SO4 solution. The improved corrosion resistance of the annealed AlCoCrFeNi2.1 EHEA was attributed to the increasing oxides proportion and thickness of passive film and the reduced composition difference between FCC and B2 phases. The B2 phase in lamellae suffered the severest corrosion.
