Current Light Metals research projects

Deformation modes in magnesium

The deformation modes activated in magnesium are being studied through conventional and in-situ tensile testing. The in-situ technique enables temperature treatments and deformation to be carried out in an SEM. The work aims to assess the influence of grain size and alloy composition on the active deformation mechanisms. Particular attention is being paid to primary and secondary twinning due to its important role in the ductility of magnesium alloys. For more information please contact Professor Matthew Barnett.

Influence of grain size on deformation behaviour

Values for the Hall-Petch slope in the literature for Mg alloys vary over the range 2-15 MPa mm1/2, a spread of nearly an order of magnitude. This project looks into the effect of grain size on the deformation stress of extruded AZ31. Apart from determining the Hall-Petch parameters, this study also examines the influence of grain size on the activation of twinning. The topic is also being explored in other materials such as titanium and TWIP steels. For more information please contact Professor Matthew Barnett.

Increasing extrusion speeds / extrusion alloy development

The slow extrusion speed required to avoid cracking of magnesium extrusions is a significant component of the manufacturing cost. In this project, a method is being developed for the rapid generation of extrusion limit diagrams. This method, which combines engineering equations for temperature rise and extrusion load with small scale laboratory extrusion tests, is then employed to examine the hot extrusion performance of a range of commercial and prototype magnesium alloys. Within these extrusion limits, the influence of the extrusion conditions on the properties of the extruded product is also being investigated. For more information please contact Dr Aiden Beer.
