High entropy alloys (HEAs) represent a novel class of advanced materials, characterized by the inclusion of at least five and up to thirteen alloying elements in near-equiatomic or equiatomic ratios. These materials have garnered significant attention from researchers in recent years due to their unique properties. Among the various methods for producing HEAs, the vacuum arc remelting (VAR) technique stands out for its ability to precisely control the melting process and rapidly solidify the melt, resulting in superior microstructural homogeneity compared to traditional casting methods.This research aims to produce a homogeneous and uniform chemical composition of the high entropy alloy AlCoCrFeNi using the VAR process. The study investigates the microstructure, elemental distribution, phase composition, and hardness of the alloy through a combination of optical microscopy, scanning electron microscopy, X-ray diffraction, inductively coupled plasma spectroscopy, and hardness testing. The findings reveal that the AlCoCrFeNi HEA forms a solid solution with a dual-phase BCC+FCC structure. Additionally, a petal-like morphology with dendritic and interdendritic regions was observed in the micrographs. The MAP analysis images demonstrated a uniform distribution and dispersion of the constituent elements. The experimentally determined weight percentages of the elements closely matched the theoretical values. The lattice parameters for the BCC and FCC phases were calculated to be 2.868 Å and 3.578 Å, respectively. The hardness of the bulk AlCoCrFeNi HEA was measured to be 505 Vickers.
