Laser-directed energy deposition is an advanced manufacturing process that can alleviate the manufacturing expenses associated with the machining and fabrication of Inconel 718 alloy. This part fabrication technique can be helpful in retrofitting broken surfaces and surface defects. This technique uses a high-power laser which makes a liquified pool on a substrate material and then the powder material is deposited into the melt pool that is further melted and solidified into a layer. The Inconel 718 is a highly demanding material in the aerospace and nuclear power sector for making parts for high-temperature applications. However, processing of Inconel parts with traditional manufacturing is costly so the industries are seeking alternate part fabrication techniques. Laser-directed energy deposition (LDED) is a suited part fabrication method but geometric inaccuracy in the built part is a major challenge. Therefore, it is necessary to study the aspect ratio of the synthesis of Inconel 718 alloy. The processing window for single linear tracks with an aspect ratio greater than two was determined to be at linear energy per unit powder feed between 4 kJ/g and 12 kJ/g and linear mass deposition rates between 6 g/min and 12 g/min in the current study.
