Advancing Micro Mechanical Testing Under Non-Ambient Conditions

Micromechanical testing methods have been continuously developed to allow understanding of deformation mechanisms operating on the length scale of microstructural features such as precipitates or grain boundaries. These techniques can range from nanoindentation which is simple to perform but has a complex stress state to micro-bending or micro-tensile data which are more complex experiments to conduct but allow for simpler stress states. We now can conduct these tests either in situ in the SEM or under aggressive environmental conditions such as corrosive environments or high temperatures. This allows for a more complete understanding of deformation mechanisms that control materials strength and failure under service conditions.

This project will work to develop micromechanical testing methods for non-ambient conditions. The exact testing methods and materials to be studied will be determined in conjunction with the student but could include metallic or ceramic materials for use in energy storage, energy generation, or transport systems.
