Abstract Scope |
Synchrotron x-ray diffraction- and imaging-based techniques are ideal tools for probing the evolution of deformation microstructures at multiple length scales and for revealing the underlying deformation mechanisms in bulk irradiated materials in situ and/or in 3D. Such tools are also advantageous in the study of additively manufactured materials. This talk will feature a few recent studies conducted at the Advanced Photon Source (APS) in Argonne National Laboratory, in particular, an in situ 3D characterizations of grain-level response to tensile deformation in neutron-irradiated Fe-9Cr ferritic alloy, and a study of porosity evolution under creep deformation in additively manufactured 316L stainless steel. The current development of the Activated Materials Laboratory, a new radiological facility to facilitate the study of nuclear materials at the APS that is built in conjunction with the APS-Upgrade project supported by the Nuclear Science User Facilities, will also be presented. |
