The Advanced Materials Design and Optimization Laboratory focuses on the tailor-made design and process optimization of advanced engineering materials, including non-crystalline and nano-crystalline alloys, bulk metallic glasses and their composites, and lightweight metals and alloys. Research includes the physics, chemistry, and metallurgy of these materials. The laboratory employs atomic/nano-granular microstructure characterizations using techniques such as AFM, SAXS, EXAFS, SANS, HRND, HRTEM, and 3DAP-FIM. Research also dynamically investigates the correlation between phase transformation and property changes.
