NSUF 25-5534: In-situ synchrotron tensile deformation characterization of a neutron irradiated Fe-9CrNew Proposal
This work will examine Fe-9Cr alloys that have been neutron irradiated in the Advanced Test Reactor to 0.5, 1, 5 and 5 dpa at either 300C or 450C. The work will perform in-situ ambient temperature tensile deformation in the High Energy X-ray Microscope (HEXM) and Activated Materials Lab (AML) at the ANL Advance Photon Source (APS). In past work, we have deformed in-situ tensile tests at the APS of the same irradiation conditions at 0.01 and 0.1 dpa. The results of those experiments and subsequent analyses have been published. One major out come of the analyses is that the irradiated materials show differences in deformation morphologies compared to the same material in the as-received condition. The work has demonstrated that it is possible to reconstruct 3D volume images of the specific grain morphologies and crystallographic orientations and their alterations throughout the tensile deformation process. The work here will extend the experiments and analyses to higher dose levels which are now possible with the opening of the AML/HEXM capabilities as part of the APS upgrade. The work also includes the use of Crystal Plasticity FEM to model the deformation characteristics. The use of CPFEM can represent the differences in grain deformation orientations as a function of irradiation conditions. CPFEM, based on real experimental data, also allows for extension of the models to other conditions where specific microstructures can be incorporated.
