Professor John Beynon joined the Department of Engineering Materials in August 2001. He took over the POSCO Chair, following the retirement of Professor Mike Sellars. John is a Sheffield B.Met. graduate, and was supervised by Mike Sellars when he studied for his PhD. He was appointed as Professor in the Department of Mechanical Engineering at the University of Sheffield in 1995, and later became Head of Department.

Research Interests

Interaction of materials science (principally physical metallurgy) and applied mechanics to solve engineering problems. Main areas: modelling the evolution of microstructure during the thermo-mechanical processing of metals, both ferrous and non-ferrous; tribology of metal forming; thermal and rolling contact fatigue and wear of rolls used in rolling mills; wear and rolling contact fatigue of railway track and wheels.

IMMPETUS

(Institute for Microstructural and Mechanical Process Engineering: The University of Sheffield)

John Beynon co-founded IMMPETUS in 1996 from his previous position in the Dept of Mechanical Engineering, in collaboration with Professor Mike Sellars (Dept of Engineering Materials) and Prof Derek Linkens (Dept of Automatic Control and Systems Engineering). A multidisciplinary research institute, IMMPETUS was established to integrate metallurgical, mechanical and thermal considerations in developing soundly based models for process planning and control.

With strong support from industry, and a major grant from EPSRC, IMMPETUS has about thirty ongoing research projects centred on modelling of industrial thermomechanical processing operations. Finite element modelling is used to determine local temperature, strain and strain rate histories during hot rolling and forging. The response of the materials to conditions of changing strain rate and temperature and to interrupted deformation typical of industrial working operations is of particular current interest. The kinetics of changes in dislocation density and subgrain size, and of strain induced precipitation, static recrystallisation and grain growth are being quantified to provide both basic understanding and inputs for computer modelling.
