| Abstract Scope |
Additive manufacturing provides the potential to tailor the composition and therefore performance of a material as a function of its spatial location on the printed component. In the case of heat exchangers, the different environments and temperatures on either side of the component may warrant different materials choices. Additive manufacturing is one method to meet this goal. To achieve higher temperatures, and therefore efficiencies, for power generation using supercritical CO2 Brayton cycles, innovative materials are sought to resist failure modes, primarily oxidation induced creep. In this presentation we present an integrated computational materials engineering (ICME) model that is being developed to design tailored materials for heat exchangers based on nickel-based alloys with superior resistant to high temperature oxidation induced creep. |
