AlCrFeNiCu high entropy alloy was fabricated by laser metal deposition technique. The laser power was varied from 1600 to 2000 W while the scanning speed was kept constant at 1.2 m/min. The deposited alloys were then exposed to annealing heat treatment conditions at 700, 900 and 1100oC for 2 hours. The microstructural analysis showed that the alloy was characterized by dual phase structure (fcc + bcc) with the amount of bcc phase solution decreasing as the annealing temperature was increased. The exposure of the alloy to annealing conditions weakened its hardness properties and promoted grain growth.
