I’m working on joint projects between Prof. David Seidman’s group at Northwestern University and Prof. Enrique Lavernia’s group at University of California, Davis. Nanostructured Al alloys, e.g. Al 7075, Al 5083 and Al-Sc alloy, are fabricated at UC Davis by cryomilling of powders followed by consolidation of cryomilled nanostructured powders via hot isostatic pressing and hot extrusion, or spark plasma sintering. The mechanical behavior of the bulk nanostructured Al alloys is also studied at UC Davis. I’m investigating the microstructures of the nanostructured Al alloys by atom probe tomography and transmission electron microscopy at Northwestern University, to understand the fundamental relationship between processing, microstructure and mechanical behavior of these nanostructured alloys.

Processing, microstructure, mechanical behavior and deformation mechanisms of nanostructured metals and alloys; advanced materials characterization by atom probe tomography and transmission electron microscopy
