PROGRAM START DATE: May 2018
Metal (high-strength steel, aluminum) processing, microstructure evolution and mechanical properties
DESCRIPTION OF RESEARCH:
Current projects include: (1) Understanding the relationship between processing parameters, microstructure refinement, and mechanical properties in an ausformed ultra high strength steel. Achieving an optimum combination of strength and ductility in the final product. (2) Strengthening Mg alloys with nano-scale stacking faults. Previous reasearch focused on deformation proccessing of commercial aluminum alloys.
