Panos Tsakiropoulos did his undergraduate studies in Mining Engineering and Metallurgy at the National Technical University of Athens and postgraduate studies and research in the Department of Metallurgy of the University of Sheffield. He joined the University of Surrey in 1986 as a New Blood Lecturer, was promoted to Reader in 1991 and was appointed to the Chair of Metallurgy of the University in 1996. He returned to Sheffield in 2006.

Research interests

Research interests are in the design and development of ferrous and non-ferrous alloys and composites for the energy, transport and aerospace industries and for biomedical applications via process-microstructure-property studies. Materials processing under equilibrium and non-equilibrium conditions is also researched as part of the alloy development. The emphasis of the research is on establishing (i) the effects of processing on the microstructure and properties of structural engineering materials and (ii) how processing can be tailored to particular engineering requirements for desirable microstructures and properties. Currently, alloys of Fe, Mo, Nb and Zr are under investigation.

  • Alloy Development: Intermetallics, Exotics, Nb Alloys, Mo Alloys
