Optimal mechanical alloying and spark plasma sintering technique to obtain nanocrystallinity, minimal contamination and enhanced oxidation behaviour in AlCoCrFeNi high entropy alloys
The effect of the phase constitution of BCC/B2, FCC, Cr7C3 and their microstructural attributes are conspicuous on the hardness properties of AlCoCrFeNi HEAs [1]. The correlation of unsolicited C and O contaminant with process parameters (milling duration/rpm) and process control agent (PCA) categorically established that contamination increases with duration of mechanical alloying (MA) [2] . It i
