Abstract Scope |
Additive manufacturing (AM) using wire feedstock is an attractive lower-cost alternative to powder-bed techniques due to less material scrap. Nickel-based superalloy Haynes 282 has applicability to high-temperature components in the energy sector and is suitable for a wide range of AM techniques due to its weldability. However, achieving an optimized processing window for LW-DED Haynes 282 superalloys requires a systematic investigation of printing parameters, such as printing energy, speed, and hatch offset. Here we screen out an optimized printing window for LW-DED with the Meltio 450 platform on the Haynes 282 superalloy through studying the effects of these printing parameters on the printing quality, microstructures, and mechanical properties. The established understanding of the printing strategy-quality-microstructure-property relationship provides valuable insights into obtaining high-quality LW-DED Haynes 282 for future practical applications.
