High Entropy Alloys (HEAs) have attracted more and more attention due to their potential beneficial mechanical, magnetic, and electro-chemical characteristics, such as high strength, high thermal stability and oxidation resistance. These promising properties offer many potential applications in various engineering fields. Sample of metallic materials were characterized using Optical Emission Spectroscopy (OES) for the experimental study. Then, one sample from the existing Aluminium (Al) material (160 × 60 × 40mm) and four samples of Magnesium (Mg) Zinc (Zn) Copper(Cu) - Iron(Fe) high entropy alloy (160 × 60 × 40 mm) were produced using the stir casting process. The potentiodynamic polarization method was used to study the Corrosion Rate (CR) of the samples in 3.65 wt.% NaCl solution. The study presents a series of results on alloys with high entropy from the Control Al high-Mg-Zn-Cu-Fe. The chemical composition of high entropy alloys used in the experimental program and the experimental alloys was done in successive five-samples. The obtained alloys were subjected to micro structural analyses, mechanical tests: Brinell hardness technique, ASTM A833
standard of hardness measurement and also dynamic impact tests using incendiary perforation projectiles. The results obtained in mechanical tests revealed high values of micro-hardness (over 600 HV0.1) as well as compressible strengths above 2000 MPa. Hence, in this work an attempt is being made to investigate and analyse the mechanical characteristics of these HEAs. The powdered samples were pelletized and sieved to 0.074mm.
