Abstract Scope |
The degradation of materials in coupled environments is often complex, non-intuitive, and highly debated. To this day, the mechanisms underlying the failure in processes ranging from the relatively simplistic hydrogen embrittlement through the much more complex irradiation-assisted stress corrosion cracking (IASCC) are hotly debated and are nuanced depending on the material system and details of the environmental exposure. In this presentation, we will detail our recent development of in-situ electron microscopy techniques to gain greater insight into the active mechanisms at the appropriate length scales. At the nanoscale, we will highlight efforts exploring in-situ transmission electron microscopy (TEM) liquid cell corrosion studies, mechanical testing in gas environments, and mechanical testing during ion irradiation. Similarly, at the microscale, we will highlight recent developments permitting in-situ scanning electron microscopy (SEM) experiments coupling irradiation, fatigue, irradiation, and corrosion. SNL is managed and operated by NTESS under DOE NNSA contract DE-NA0003525. |
