Heat exchangers are essential components in various heat management systems like aerospace, automotive, and power generation equipments. Compactness is one of the primary criteria used for evaluating a heat exchanger, which is calculated as the heat transfer area to volume ratio. Additive manufacturing techniques can effectively be used to fabricate complex-shaped heat exchanger geometries with very high surface area-to-volume ratios. The operating conditions for heat exchangers in next-generation power plants are demanding temperatures up to 720⁰C, pressures of 200 bar, and the potential to resist corrosion and oxidation. Nickel-based superalloys are suitable materials for manufacturing compact-type heat exchangers for high-temperature applications. Haynes 282 alloy is one such alloy that offers a balance of long-term creep strength, thermal stability, oxidation resistance, weldability, manufacturability, and repairability. In this research work, the suitability of Haynes 282 alloy to manufacture compact, high-temperature heat exchangers is investigated through microstructural and mechanical studies of the Laser Powder Bed Fusion manufactured heat exchanger parts.
