Abstract Scope |
The success of nanoindentation has opened up a world of small-scale mechanical testing in a range of extreme environments. In this presentation, we will highlight the potential of coupled environments during quantitative mechanical experiments. The development of commercial transmission electron microscope (TEM) nanoindentation stages has permitted a range of quantitative indentation, pillar compression, three-point bend, and tensile loading conditions that are predominately limited by the sample preparation technique chosen and one’s imagination. These emerging capabilities permit a vision for in-situ TEM high cycle fatigue, high temperature creep, irradiation induced creep, and stress corrosion cracking. Initial results from the fatigue and creep environments will be demonstrated in materials ranging from high purity metals through scandium stabilized zirconia. Finally, this presentation will highlight the recent developments to explore coupled thermal, mechanical, and radiation environments through SEM scale quantitative mechanical testing. SNL is managed and operated by NTESS under DOE NNSA contract DE-NA0003525. |
