Abstract Scope |
The high strength-to-weight ratios of aluminum alloys is of major interest in the aerospace industry. There are many Directed Energy Deposition (DED) techniques that have been used to fabricate aluminum alloy components. In this study, several aluminum alloys were fabricated using a variety of DED techniques, such as arc-wire DED and additive friction stir deposition (AFS-D). Our presentation will discuss the microstructure, surface finish, and mechanical properties of the as-built aluminum alloys. The alloys investigated in this study include: AA2219, AA4047, AA2319, and AA6061. EBSD and EDS were used to characterize the microstructure. Additionally, hardness testing and surface roughness were measured. This research will highlight the differences between DED techniques and aluminum alloys printed using these techniques. |
