A nickel aluminum bronze (NAB) wire with chemical composition of Cu-8.64Al-4.2Ni-3.2Fe V(wt%) was processed via directed laser energy deposition. This study investigates the effects of process parameters and post process heat treatment on the NAB microstructure and resulting mechanical properties. Single track depositions were measured and characterized for macro defects to determine optimal parameter sets. Laser powers of 800-1200 W and print head traverse speeds of 300-900 mm/s were varied in nitrogen atmosphere to produce characterization samples. Scanning electron microscopy was utilized to observe the microstructure and elemental dispersion. Energy dispersive X-ray spectroscopy revealed a single ferritic phase of the as printed sample. Annealing heat treatment of 675 C for 6 hours was performed on the as printed DED sample. Microhardness and tensile tests were conducted to obtain mechanical properties. The microstructures and mechanical properties of the as printed and heat-treated samples were analyzed and compared.
