| Abstract Scope |
Wire-arc additive manufacturing (WAAM) offers a promising route for producing large-scale Cu-30Ni components with tailored properties for marine and industrial applications. However, the anisotropic nature of WAAM deposits necessitates a thorough understanding of how build orientation influences microstructure and mechanical performance. This study investigates the effect of X-Y deposition orientation on tensile properties, fracture toughness (impact, quasi-static), fatigue crack growth (FCG) resistance, and hardness of WAAM-fabricated Cu-30Ni alloy.
Samples were excised from large-scale WAAM deposits (Xmm x Ymm x Zmm) to determine the effects of sample orientation on both microstructure and mechanical behavior. The presentation will summarize the processing conditions, followed by microstructure characterization and SEM fractography of the tested samples. Future work will be examining the environmental effects on certain properties. |
