Nanotech Metallurgy is an interdisciplinary domain of materials science and engineering, manufacturing, and nanoscience and engineering to study how nanophases (both ex situ and in situ) can be engineered and applied to significantly improve the processing/manufacturing, micro/nano-structures, and physical/chemical/mechanical behaviors of metals and alloys. Recently the discovery of a nanoparticle self-dispersion and stabilization mechanism in molten metals further paves a scientific and technical foundation for scalable manufacturing in Nanotechnology Metallurgy.
It should be noted that Nanotech Metallurgy has a much wider scientific and technological reach beyond the concept of metal matrix nanocomposite, which focuses on how nanoparticles (generally of high volume fractions) are used to tune the material properties only. Nanotechnology Metallurgy is poised to create exciting processing/manufacturing space while pushing the performance envelope of metals to meet energy and sustainability challenges in today’s society.
Our lab focuses on various scientific and technological aspects on how nanotechnology can be applied to break metallurgical barriers, enabling unprecedented micro/nano-structure control and property tuning for metals and alloys. Some examples include, but not limited to: >> Read more about our publications
