Research Interests
Professor Dunand 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) 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 or selective laser melting. An additional area of study is the use of synchrotron X-ray radiation to study strains, phase composition and tomography in battery materials, structural composites, archeological alloys, r selective laser melting and biomineralized materials (bone and tooth).
