Abstract Scope |
Developing alloys for Additive Manufacturing (AM) presents many challenges compared to more traditional processing methods such as casting. Specifically, exploring large composition space requires various feedstock alloys (e.g., powders) that can be expensive and time consuming to produce. Another challenge is mapping out processing-structure-property relationships typically requires a large number of bulk samples to be printed. We have used directed energy deposition (DED) to rapidly synthesize Al alloy libraries over a wide range of compositions. The relatively small samples (~ 5 x 5 x 5 mm3) are ideal for instrumented scratch testing, which unlike various hardness testing methods (e.g., Vickers) can provide greater insight into the bulk mechanical response including ductility and fracture toughness. Using this combined approach, we have rapidly identified Al alloy compositions that are both compatible with laser-based AM synthesis and show excellent strength and ductility. |
