Research Interests

Physical and Mechanical Metallurgy of Multiphase Metallic Materials. My 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: 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. Metallic foams: Foams based on titanium (Ti, Ti-6Al-4V) and nickel for aerospace or implant implications; Foams from shape-memory alloys (Ni-Ti and Ni-Mn-Ga) for biomedical implants or actuators; Freeze cast Cu-, Co-, Fe-, W- and Ni- foams for electrodes in energy applications; 3D printed metallic scaffolds using ink precursors. 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, r selective laser melting and biomineralized materials (bone and tooth).
