Abstract Scope |
Current state-of-the-art alloys that are used for turbine or high-temperature energy applications, are usually nickel-based (super)alloys. However, the use of these alloys have fundamental limitations such as their melting temperatures, their microstructure instability under irradiation or they limited corrosion resistance. Compositionally Complex Alloys (CCAs) represent a class of alloys that have shown promising properties in extreme environments but their development is limited by the almost limitless compositional and phase space to explore. A comprehensive high-throughput platform has been developed to design CCAs resistant to extreme environment based on CALPHAD thermokinetics modeling, in-situ alloy processing using direct energy deposition additive manufacturing and novel corrosion and irradiation high-throughput testing methods. Examples of this high-throughput platform will be presented including development of NbMoTiTaAlCr CCAs for turbine applications, FeCrMnMoNi CCAs for structural materials in high-temperature molten salt energy systems, and FeCrMnNi and light/heavy refractory CCAs for advanced fast nuclear reactors applications. |
