Abstract Scope We have studied equiatomic quinary AlCuFeMnMg, and non-equiatomic octonary AlSiCrMnFeCoNiCu high entropy alloys (HEA) processed through various non-equilibrium routes. The equiatomic MgAlMnFeCu HEA was synthesized by mechanical alloying followed spark plasma sintering (SPS). Similarly, the Al40(SiCrMnFeCoNiCu)60 (at%) HEA was synthesized by vacuum induction melting (VIM). These non-equiatomic HEAs were further subjected to cryomilling (CM) followed by SPS. The phase evolution of these HEA was studied using X-ray diffraction (XRD) and transmission electron microscopy. The morphology and chemical composition of powder particles were examined through SEM and EDX. Thermal stability of these HEAs through in-situ heating XRD and DSC was investigated. The mechanical properties of these alloys were ascertained through instrumented microhardness and compressive testing. The density of these equiatomic and non-equiatomic HEAs was found to be 4.946 ± 0.13 g/cc and 5.086 ± 0.15 g/cc respectively. Various thermodynamic parameters were considered for understanding the phase evolution and their stability.
