| Abstract Scope |
The development of trusted models in extreme environments requires the direct correlation, refinement, and validation from experimental tests under similar conditions. This coupling is often difficult due to the engineering limitations associated with performing experiments on the associated length and time scales. This presentation will highlight some of the recent advancements made to enhance the extreme thermal, mechanical, and electrical shock conditions that can be achieved within a transmission electron microscope (TEM), as well as recent improvements in the temporal resolution. To highlight the potential of this approach, we will present the coupling of multi-scale modeling to experimental results in materials ranging from stainless steel to carbon fiber composites to additively manufactured refractory high entropy alloys. Finally, the presentation will conclude with recent in-situ extreme scanning electron microscopy (SEM) developments and the potential coupling to mesoscale modeling.
