| Abstract Scope |
Generation 3 Concentrated Solar Power Systems are being targeted for operating temperatures greater than 700°C. Ni-based alloys such as Haynes®230®, Haynes®282® and IN®740H which have the potential to satisfy the high temperature mechanical property requirements and corrosion resistance are being considered for this application. Components such as piping, valve fittings may be manufactured at a lower cost using a casting process to reduce the overall system cost. This talk will present the effect of casting and subsequent heat-treatment on the microstructure and high temperature tensile properties of Haynes®282® and will compare these with that obtained using 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). |
