Effect of aluminium content and grain size on oxidation behavior of AlxCoCrFeNi (x=0, 0.3, 0.6, 1 mole) high entropy alloy
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 mechanical alloying (MA) followed by consolidation through spark plasma sintering (SPS). Alloys with x = 0 and 0.3 show single phase FCC structure, whereas those with x = 0.6 and 1 have dual phases – FCC and BCC. Interestingly, synthesis t
