This study investigates the use of direct energy deposition (DED) process to repair Inconel 718 components. Inconel parts repaired using optimised parameters exhibited mechanical performance comparable to the wrought Inconel tested under 4-point bend and cyclic loading. The columnar DED microstructure is modified using inoculants, resulting in a finer microstructure with improved strength.
