| Abstract Scope |
Advancing manufacturing and engineering technology of microchannel heat exchangers has been identified as one of the most critical aspects of the Brayton cycle, utilizing supercritical CO2 above 700oC and 8 MPa. This project investigates the ability of Haynes 230 to be used in microchannel heat exchangers. Diffusion bonding offers tight dimension tolerances, which is critical to the manufacturing of heat exchangers, while selection of Haynes 230 offers excellent corrosion resistance and creep resistance at elevated temperatures. Stacks of Haynes 230 sheets, 0.5 mm thick, were diffusion bonded together to assess the mechanical properties of the diffusion bond. Mechanical properties of the bond are discussed. |
