Wynne, Bradley P - University of Sheffield - Department of Materials Science and Engineering

个人简介

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.

研究领域

On appointment as a lecturer we quickly developed a number of independent research themes, which has led to a number of innovative microstructure characterisation and processing solutions, particularly for titanium, but also in magnesium alloys and steels. In 2003, in collaboration with Servotest Ltd, we designed the world unique Arbitrary Strain Path machine, which was installed in 2004. This machine is capable of either concurrent or sequential torsion/reverse torsion and tension/compression at high temperature and strain rates. We have also instigated and developed industrial led projects with Firth Rixson, Timet UK, Magnesium Elektron, TWI, Tata, Boeing, Rolls Royce, Sheffield Forgemasters, and RTI. For example, working with Timet UK on understanding the impact of process route on microstructure and crystallographic texture in safety critical aerospace titanium alloys. This work also resulted in the development of a computer code to reconstruct the high temperature beta microstructure and texture from the as-transformed low temperature alpha microstructure, which is now used in a number of labs around the world.
