Abstract Scope |
Multiphase FeMnNiAlCr high entropy alloys (HEAs) are being considered as tubing materials for next generation concentrated solar power systems because of their excellent mechanical properties, good oxidation resistance, and the exceptional solar absorptance of their native oxides. This talk will present research on strain-rate jump tests and the creep behavior of FeMnNiAlCr HEAs at temperatures of 873-1023 K. The effects of recrystallization and additional solutes, which were both shown to improve the high temperature strength and creep resistance, will also be discussed. The microstructures of the alloys both before and after creep were characterized using a combination of XRD, a SEM and a TEM. This work was supported by the US Department of Energy Grant. |
