NSUF 16-CINR-10696: Understand the phase transformation of thermal aged and neutron irradiated duplex stainless steels used in LWRs
Complemented by the TEM/APT studies and ex-situ mechanical tests on duplex stainless steels from our existing research program, the results from X-ray diffraction/EXAFS/WAXS in-situ tensile test will provide an unprecedented multi-scale understanding on phase separations, precipitate nucleation and growth, and lattice straining of different phases in the thermally aged and/or neutron irradiated duplex stainless steels. The microstructure interpretation will be correlated with mechanical performance. The project outcomes will directly contribute to the DOE/NE LWRs sustainability program by providing a mechanism for more accurately evaluating the performance of the duplex stainless steel components at the extended reactor life.
