Abstract Scope |
This presentation will detail the utility of coupling automated crystallographic mapping (ACOM) and in-situ transmission electron microscopy (TEM) to gain a richer understanding of local structural defects impact on the nucleation, motion, and overall evolution of dislocations and other defects as they respond to thermal, mechanical, and radiation environments. Examples include in-situ TEM high-cycle fatigue of nanocrystalline platinum, dislocation transmission across a grain boundary in stainless steel, channeling impact of sputtering during self-ion irradiation of gold nanorods, and grain growth during self-ion irradiation of nanocrystalline gold thin films will be highlighted in this presentation. In a subset of these examples, this presentation will highlight the ability of ACOM to directly provide input and subsequent refinement to both molecular dynamics and mesoscale modeling. Finally, this presentation will provide the development status associated with the in-situ TEM coupled with ion and laser irradiation at the Tennessee Ion Beam Materials Laboratory. |
