Abstract Scope |
Achieving radiation tolerance in crystalline materials will require a thorough understanding of defect evolution and corresponding material responses to ion bombardment. Tailoring grain boundaries to behave as enhanced defect sinks poses a potential solution toward the development of more radiation tolerant materials; however, critical nuances illustrating the microstructural response of grain boundaries under irradiation have yet to be explained. In particular, the relationship between GB structural states and their effect on the rate of defect absorption is unclear. In this study, we utilize automated object detection models of in situ TEM experiments to offer insight into transient GB states and analyze state transitions with rate theory models and molecular dynamics simulations. By providing an indicator of changes in GB absorption mechanisms, we move closer to explaining GB metastability with the onset of radiation damage and the deviation of interfacial responses in pure and compositionally complex materials. |
