In this study, creep performance of a potential heat exchanger alloy, Haynes 230 was investigated. To simulate mechanical performance of a heat exchanger, sheet material of Haynes 230 transient liquid phase (TLP) bonded together. Sheets were plated on both sides with a Ni–P compound, subsequently stacked and TLP bonded together. Duplicate creep tests show low scatter in creep results, meaning a good repeatable joint was formed by TLP bonding. Overall creep performance showed less ductility and shorter times to failure than specimens originating from plate material. Lastly, evolution of a phosphorous compound at the bond line was observed and thought to potentially reduce ductility of the TLP bonded alloy.
