Environmentally assisted cracking and failure is fundamentally a complex process involving multiple stressors that initiates at the atomistic scale. Although the theory and modeling effort has incorporated a multi-scale approach, this has largely been limited in the experimental effort due to the difficulty of observing sample with nanometer resolution during exposure to controlled coupled environments. This presentation will highlight recent developments at Sandia National Laboratories (SNL) to advance the capabilities to study coupled extreme environments via in-situ Transmission Electron Microscopy (TEM). This will include efforts to explore in-situ TEM ion irradiation, thermal, gas, mechanical, and environmental exposure in various combinations in a range of complex materials systems. SNL is managed and operated by NTESS under DOE NNSA contract DE-NA0003525.
