Eric Palmiere joined the Department in June 1997 from the University of Pittsburgh, USA, where he was an Assistant Professor from 1993-97. He is the Director of the Thermomechanical Processing Laboratory.
Research interests
His research involves the microstructural evolution (utilising experimental techniques together with modelling techniques), and the subsequent development of mechanical properties, during the thermomechanical processing of both ferrous and nonferrous alloys. In his research, a wide range of mechanical tests are employed, including laboratory simulations of industrial metalworking processes (e.g., rolling, forging, extrusion etc.). Additionally, this research relies upon the quantitative characterisation of microstructure using a number of different techniques including light, scanning and transmission electron microscopy. This work has led to empirical relationships between deformation processing parameters (e.g., temperature, strain, strain rate and interpass delay time) and the resultant microstructure for a given alloy composition. In many cases, his research is interdisciplinary, involving the Departments of Mechanical Engineering and Automatic Control and Systems Engineering as part of the Institute for Microstructural and Mechanical Process Engineering: The University of Sheffield (IMMPETUS).
Although a number of alloy systems including aluminium alloys, metal matrix composites (MMCs), titanium aluminides and permanent magnetic materials have been studied, the focus is primarily on ferrous alloys such as stainless, microalloyed steels and associated model alloy steels. His work on the thermodynamic behaviour of NbC, and of its subsequent precipitation behaviour in microalloyed austenite has been recognised internationally, with the award of the Charles Hatchett Prize from the Institute of Materials (1995). He is particularly interested in developing a basic understanding between those softening (i.e., recovery, recrystallisation) and strengthening (i.e., solid solution, precipitation) mechanisms which occur either in austenite or in ferrite.
