Abstract Scope |
This presentation will provide an overview of recent research from the National Center for Additive Manufacturing Excellence (NCAME) on aluminum alloys (including Scalmalloy, F357, AlSi10Mg, A6061-RAM2, and A1000-RAM10) fabricated through laser powder bed fusion (L-PBF) and laser powder directed energy deposition (LP-DED). These aluminum alloys --some of them designed specifically for additive manufacturing-- exhibit proper compatibility with laser-based additive technologies and have attracted significant attention from aerospace industry. Tensile and fatigue tests of the aluminum alloy specimens, in both L-PBF and LP-DED forms, have been performed at temperatures ranging from -196°C to 400°C (for tensile tests) and from -196°C to 200°C (for fatigue tests). A comparison of tensile deformation and fracture characteristics as well as fatigue crack initiation and growth behavior of the alloys will be presented and discussed in the context of their microstructure and defect contents. |
