Abstract Scope |
There is significant interest in the development of Nb-based alloys for continuous use in turbine applications at 1300°C. These alloys are expected to have excellent high temperature creep properties, good room temperature strength and ductility, good processability, preferably be comparable in density to current Ni-based alloys, and be compatible with coatings that provide oxidation resistance at these temperatures. This presentation will highlight some of the challenges in developing Nb- alloys that possess the appropriate balance of properties. This work was supported by the US Department of Energy – ARPA-E ULTIMATE Program. This research was conducted by Oak Ridge National Laboratory, which is managed by UT Battelle, LLC, under contract DE-AC05-00OR22725 with the US Department of Energy (DOE) |
