| Abstract Scope |
IN939, a Ni-base superalloy, is utilized in land-based gas turbine engines due to its excellent high-temperature microstructural and mechanical stability and high corrosion resistance. Traditional manufacturing techniques like casting and forging cannot produce intricate geometries in a single step. Powder bed fusion-laser beam (PBF-LB) offers advantages such as design flexibility and single-step production of complex geometries with minimal material waste. While IN939 has recently been manufactured using the PBF-LB process, further research is needed to comprehend the effects of process parameters, particularly scanning strategies, on its material properties such as relative density, defect formation, microstructure, residual stress, and surface roughness. This study investigates the influence of different PBF-LB scanning strategies on these material properties of IN939. |
