In the present study, a high entropy alloy (HEA) consists of six alloying elements was synthesized using Disintegrated Melt Deposition (DMD) technique. The alloy having a chemical composition of Mg35Al33 Li15Zn7Ca5Cu5 (atomic pct.) was designed based on non-equiatomic ratio and high entropy of mixing. Most of the HEA alloys currently developed were refractory alloy systems for which most of the HEAs compositions exhibited high-density values of more than 10 g/cm3. For the current alloy development, particular emphasis was placed on the development of light weight HEA alloy. The developed alloy, Mg35Al33Li15Zn7Ca5Cu5 exhibited a density of 2.27 g/cm3 which is lower than that of aluminium (2.7 g/cm3). The formation and presence of phases and microstructural evolution of the developed alloy were examined using SEM, EDX and XRD analyses. Mechanical properties were determined in terms of macro and microhardness and compression testing.
