Abstract Scope Understanding the evolution of material performance in-situ under extreme conditions remains a great challenge. Emergent behavior in these conditions, such as the transition from incubation to steady state void swelling under high-dose radiation, is often difficult to capture with ex-situ data sampling protocols. Recently, the ability to non-destructively recover multi-property information in-situ, during exposure to extreme conditions, has been demonstrated using transient grating spectroscopy (TGS). This all-optical method returns elastic mechanical and thermal transport properties with second-scale time resolution, often sufficient to capture emergent material behavior. Here, recent work using this methodology to track the evolution of Ni-based solid-solution alloys under high temperature exposure to ion beam irradiation using the in situ ion irradiation TGS (I3TGS) beamline at Sandia National Laboratories will be described. Initial considerations for experiments on nanocrystalline alloys subject to both extreme temperatures and strains will also be discussed, showcasing the growing utility of this methodology.
