Abstract Scope |
Generation 3 Concentrated Solar Power Systems are being targeted for operating temperatures greater than 700°C. Ni-based alloy such as Haynes®282® has the potential to satisfy the high temperature mechanical property requirements but cost and availability are major factors to be considered in its use. Components such as piping, pump and valve bodies can be manufactured at a lower cost using casting processes and hence can be produced on demand. This talk will present the effect of casting processes and part geometry on the microstructure, high temperature tensile and short-term creep properties of Haynes®282® and compare these with that obtained from traditional wrought processing. This work was supported by the US Department of Energy - Solar Energy Technologies Office Concentrating Solar Thermal Power 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). |
