| Abstract Scope |
Copper-based feedstocks are of interest to the marine as well as aerospace industries for their strength and corrosion resistance as well as excellent electrical and thermal conductivity. Furthermore, gas metal arc directed energy deposition (GMA-DED) is an ideal method to produce large scale structural components for these applications. In this study, a wide range of copper-based feedstocks including a nominally pure copper, silicon bronze, aluminum bronze, nickel aluminum bronze, and GRCop-42 alloy wires were printed using GMA-DED, and the solidification structure and weldability were evaluated. Experimental measurements of the solidification structure were compared to model predictions and other published work. The results of this work are expected to provide a deeper understanding of welding metallurgy of copper-based feedstocks to enable a broader application of these materials for structural applications. |
