Metallic nano-composite materials with fcc/fcc or fcc/bcc interfaces show exceptional strength, resistance to irradiation, and high thermal stability. In order to better design metallic nano-composite systems, it is necessary to understand the deformation mechanisms. Many variables affect the properties such as layer thicknesses, lattice mismatch, and crystal structures. By understanding the effects and altering these, better materials may be designed.

My primary project investigates defect interactions with interfaces in these metallic nano-composite materials. The high density of interfaces present leads to different deformation mechanisms as compared to coarse-grained material and can force one material to respond in an unpredicted manner. For example, twinning in one system may force the unlikely response of twinning in the other. This leads to the interesting question of how this deformation response is communicated across the interface. It is my goal to understand this communication at the atomic scale by using TEM to characterize the interface reactions and interactions.
