Physical and Mechanical Metallurgy of Multiphase Metallic Materials

Our research focuses on metals containing second phases (ceramic, intermetallic, metallic) or pores, 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.
2. Metal matrix composites: magnesium with superconducting MgB2 fibers.
3. Metallic foams:
- Foams based on titanium (Ti, Ti-6Al-4V or NiTi) created by entrapment and subsequent expansion of argon bubbles or by use of leachable space-holder for biomedical applications;
- Fe- or Ni-based foams, synthesized by sintering of powders with space-holders or infiltration of hollow spheres beds or salt beds, for fuel-cell applications;
- Zr- and Mg-based amorphous alloy foams processed in the liquid state.

An additional area of study is the use of synchrotron X-ray radiation to study strains, phase composition and texture in technical metallic composites, archeological alloys, and biomineralized materials.
