Abstract Scope |
One hurdle preventing wider implementation of Concentrated Solar Power is component cost. Heat exchangers are a large fraction of that cost, stemming from the requirement of high-temperature materials to withstand extreme conditions. However, by replacing the material at the low-temperature side of the heat exchanger with a lower cost material, the recuperator continues to perform adequately while minimizing the overall cost. This work suggests a novel combination of Laser Powder Bed Fusion and Directed Energy Deposition Additive Manufacturing. IN625 is deposited onto SS316L to provide functionally graded material (FGM) samples for mechanical and microstructural characterization. Two types of transitions are made between the alloys, namely, a direct transition and a 50/50 mixture of both alloys. Tensile properties of the FGMs are compared to both additively manufactured and wrought manufactured monotonic alloys. Scanning Electron Microscopy, Electron Backscatter Diffraction, and porosity analysis (through Computed Tomography scanning) are also conducted. |
