Bradley Wynne joined the Department of Materials Science and Engineering in February 2002 having previously been an IMMPETUS Research Fellow in the Department of Mechanical Engineering, University of Sheffield. Before coming to Sheffield he worked as a Research Fellow in the Department of Materials Engineering, Monash University, Australia on Ultra-low carbon steels. He also gained his BEng and PhD from Monash. He is an active member of the IMMPETUS research group. For more information on IMMPETUS go to http://www.immpetus.group.shef.ac.uk/.
He is currently Course Director of the Advanced Metallic Systems Centre for Doctoral Training hosted jointly by Sheffield and Manchester Universities. This is a four year enhanced PhD programme focussed on producing the next generation of research leaders in metallic systems. If you wish to have more information on this course please go to http://www.metallicscdt.co.uk/.
Dr Wynne is also coordinator of Master of Metallurgy (Advanced Metallurgy), MSc(Eng) in Aerospace Materials and PhD with Integrated Studies (Advanced Metallurgy) postgraduate courses. If you wish to have more information on these course please go to http://www.shef.ac.uk/materials/prospective_pg.
Research interests
Research interests focus on the thermomechanical processing of metals and alloys, particularly the interrelationship between the constraints imposed by the deformation conditions and the constraints on flow behaviour generated by crystal structure and crystallographic texture, which in turn determines deformation microstructure evolution. Currently his major focus is on the effects of non-linear strain paths on microstructure evolution and the application of high resolution electron back scattered diffraction for microstructure quantification. The overall aim of this research is to develop true internal state models for microstructure evolution to replace our current empirically based models which are often inadequate when deformation conditions are complex. Current work involves all major engineering metals and alloys including aerospace titanium, nickel superalloys, heat-treatable aluminium alloys, wrought aluminium alloys, duplex stainless steel, austenitic stainless steel, C-Mn steel and Magnesium.
