I have investigated compositional changes that occur at the subnanometer scale in various aluminum alloys and steels to understand the microstructure-mechanical property relationships and mechanisms of microstructure formation. I am also interested in characterizing the microstructures of alloys are subjected to severe plastic deformation, including radiation damage and fablicated by non-equilibrium methods, i.e., thin film or powder processes. These non-equilibruim processes produce materials with unique microstructural features, for example ultrafine grained materials, having both scientific and industrial importance. I have also designed several instruments to fabricate metallic thin films and nano-size powders using various methods such as physical vapor deposition (PVD) in order to perform microsturctural characterization.
Analytical techniques are essential components of my research activities. I have experience with various modern analytical techniques, especially subnanometer level chemical and structural analytical instruments, including:
- High-resolution transmission electron microscopy (HRTEM)
- Analytical microscopy (EDS, EELS and GIF)
- Microstructural characterization using ion beam accelerator
- Three-dimensional atom probe field ion microscopy (instrumentation and software development )
- Fablication of metallic thin film and nano-size particle by PVD
A complete list is available.
