Research Interests
Physical and Mechanical Metallurgy of Multiphase Metallic Materials
Our research focuses on metallic alloys, composites, and foams, with particular emphasis on measuring and modeling their mechanical properties. Three main families of materials are being investigated:
1. Dispersion-strengthened metals: aluminum with Al3X (X=Sc, Ti, Zr, Li, rare-earth elements) nano-size precipitates, for energy-efficient transportation, nickel and cobalt-base superalloys with L12 precipitates, and iron-base ferritic superalloys with B2 precipitates.
2. Metal matrix composites: magnesium with superconducting MgB2 fibers and aluminum composites.
3. Metallic foams:
- Foams based on titanium (Ti, Ti-6Al-4V) and nickel for aerospace or implant implications;
- Foams from shape-memory alloys (Ni-Ti, Ni-Mn-Ga) for biomedical implants or actuators;
- Fe- or Ni-based foams for fuel-cell interconnects;
- Zr-based amorphous alloy foams for armor and other high-stregnth applications;
- Au foams with nano-size porosity for catalysis.
An additional area of study is the use of synchrotron X-ray radiation to study strains, phase composition and texture in battery materials, structural composites, archeological alloys, and biomineralized materials (bone and tooth).
