Determination of structural, tribological, isothermal oxidation and corrosion properties of Al–Co–Cr–Fe–Ni–Ti–Cu high-entropy alloy

In the present work, Al10Co24Cr10Fe15Ni34Ti6Cu1 (at.%) was obtained high entropy alloy (HEA) with vacuum arc melting. The microstructure, tribological properties, oxidation, and corrosion resistance of the HEA were detailly investigated. The faced-centered cubic solid solution structure was observed in the microstructure. SEM analysis shows that Fe, Co, and Cr elements are dominant in the dendrite region, the interdendritic regions are...
