Abstract Scope |
Additive manufacturing technologies have gained attention in the aerospace industry. These technologies enable a reduction in part count, the production of complex shapes, and shortened fabrication times. In the aerospace industry, nickel-based alloys are commonly used due to their high corrosion resistance and strength at elevated temperatures. However, with the advent of these technologies, constant investigation into the weldability of these alloys is necessary. This research focuses on the transverse varestraint weldability testing of solution-strengthened Ni 625 and precipitation-strengthened Ni 718, fabricated using laser powder bed fusion and direct energy deposition. Both alloys were tested in the stress-relieved condition and compared to their wrought counterparts. Additionally, oxygen and nitrogen measurements were taken and correlated with the microstructure. Electron Backscatter Diffraction (EBSD) images of each process are also compared. |
