Effects of Ni Addition on the Microstructure and Electrochemical Corrosion Property of AlFeCoCrCuNi_x High-entropy Alloys AITranslate
Abstract AITranslate
The influences were investigated of different amounts of Ni element on the microstructure and electrochemical corrosion property of AlFeCoCrCuNix(x=0,0.25,0.5,1)high-entropy alloys by XRD,SEM,EDS and electrochemical polarization curves.The results show that all the alloys exhibit dendritic microstructure with composition segregation,and Cu element is enriched in interdendritic boundaries.Adding a small amount of Ni element results in the formation of granular Al-Ni new phase.With the increase of Ni content,the granular Al-Ni new phase develops into a massive phase distributed between Curich boundary and dendrite.Furthermore,the addition of Ni element improves the corrosion resistance of AlFeCoCrCuNix(x=0,0.25,0.5,1)alloy in 3.5% NaCl solution.And AlFeCoCrCuNi0.5alloy exhibits the optimal corrosion resistance.
