Abstract Scope |
Understanding deformation, fracture, and failure of materials in complex and extreme environments is difficult to predict due to the overlapping and potentially deleterious mechanisms that might be active. This presentation will highlight recent advancements of in-situ scanning and transmission electron microscopy capabilities at Sandia National Laboratories to provide a wide combination of extreme environments. These capabilities permit nanoscale structural evolution during a range of environments including very high temperature, high cycle fatigue, displacement damage, corrosion, and combinations thereof. In contrast to the real-world extreme environments, these studies permit the ability to deconvolute the factors greatest impacting the underlying deleterious mechanisms. Sandia National Laboratories is a multimission laboratory managed and operated by National Technology & Engineering Solutions of Sandia, LLC, a wholly owned subsidiary of Honeywell International Inc., for the U.S. Department of Energy’s National Nuclear Security Administration under contract DE-NA0003525. |
