Abstract
The objective of this work is to present recent advancements in transmission electron microscopy (TEM) in situ depth-sensing mechanical testing of nuclear and irradiated materials. This work specifically emphasizes those advancements enabled by the US Department of Energy (DOE) Nuclear Science User Facilities (NSUF). TEM in situ depth-sensing mechanical testing offers the potential for gaining unprecedented insight into mechanical behaviors of materials because it uniquely couples quantitative mechanical measurements with qualitative microstructure-scale observations of plastic phenomena. The nuclear and irradiated materials research community has a growing interest in TEM in situ mechanical testing because material volumes less than a cubic micrometer can be tested. Such a configuration could open unprecedented opportunities for accelerating material qualification by ion irradiation, or reducing the cost of in-pile neutron irradiations.
