| Abstract Scope |
Understanding the thermodynamic stability of materials with small second phases and other heterogenous structures often requires the resolution provided by advanced electron microscopy techniques. In addition, many of the coupled extreme environments seen in nuclear, space, geological, and other harsh environments, create a great number of possible conditions in which new phases and microstructures might be present. In this presentation, we will highlight how advanced electron microscopy techniques can be utilized to characterize everything from solid state noble gasses trapped in ordered arrays of nanoscale bubbles through amorphous intergranular films created or modified through extreme thermal and radiation conditions. This presentation will highlight combined in-situ experiments with controlled radiation damage and ion implantations, while at temperatures ranging from 77K to nearly 2,000K and under quantified mechanical loading provided by the in-situ ion irradiation transmission and scanning electron microscope. SNL is managed and operated by NTESS under DOE NNSA contract DE-NA0003525. |
