CX-270237: Understand the Phase Transformation of Thermally Aged and Neutron Irradiated Duplex Stainless Steels Used in LWRs – University of Florida

The University of Florida, in collaboration with Argonne National Laboratory (ANL), proposes to use the capability of the high energy X-ray MRCAT facility at ANL, including X-ray diffraction (XRD), Extended X-ray Absorption Fine Structure Specroscopy (EXAFS) and in-situ tensile testing with wide angle X-ray scattering (WAXS) to probe the elemental segregation, phase precipitations, and lattice strain status under tensile load of different phases in selected cast austenitic stainless steels (CASS) and welds.
