Abstract Scope |
Additive Manufacturing (AM) has enabled the production of many new metal composites that are directly bonded to one another, allowing for continuous changes in material properties across their interface. Inconel 718 is a commercially available nickel alloy with high strength properties but low thermal conductivity. GRCop-84 is a thermally conductive copper alloy that can compensate for Inconel’s low conductivity. In this work, these two alloys are bonded together in a layered fashion to test the feasibility of forming a high-strength, high-conductivity composite material. Equilibrium phase simulations have suggested the presence of brittle intermetallic phases within the bond, so the benefits of a pure nickel interlayer are also studied. Energy Dispersive X-Ray Spectroscopy (EDS) is used to quantify the presence of different phases in the bond. |
