Effect of Al content on oxidation behavior of AlxCoCrFeNi (x=0,0.3,0.6,1mole) arc-melted high entropy alloys
One of the most anticipated properties of high entropy alloys (HEA) is excellent oxidation resistance. AlxCoCrFeNi (x=0,0.3,0.6,1 mole) HEAs were synthesized by arc melting route, followed by 4 remelting operations to ensure compositional homogenization. Alloys with x = 0 and 0.3 show single phase FCC structure and x = 1 have intricate BCC+B2 structure, whereas x = 0.6 have dual phases – FCC and B
