Aluminium @ Birmingham Mark Jolly 27th March 2009

Academic Staff Dr Mark Jolly Dr Bill Griffiths Prof Nick Green

Dr W.D Griffiths Heat transfer coefficients for modelling of gravity and low-pressure die casting Life-cycle of double oxide film defects in Al alloy Improving the quality of Lost Foam castings Positron Emission Particle Tracking of radioactive inclusions during mould filling.

Professor Nick Green A holistic approach to development of high performance components Development of a quiescent metal casting technology Optimisation of heat treatment cycles for high performance castings Alloy and process development for structural aluminium components operating at 250 °C

Professor Nick Green Casting technique for thin wall (0.4 mm) aluminium components Characterisation of life cycles of bifilm defects in cast aluminium alloys  Research on term ambition to predict casting performance based upon filling and everything that follows

Dr Mark Jolly Modelling shape casting (and other) processes PhD developing software techniques for identifying entrainment events in liquid aluminium From October £800k project. Energy usage in the foundry industry Discussion with GKN

Possible “healing” of a “bifilm”? Dr Bill Griffiths Studying the life-cycle of double oxide film defects in Al alloy. Possible “healing” of a “bifilm”? Rate of consumption of an air bubble trapped in liquid Al studied using real-time X-ray imaging.

Dr Bill Griffiths Improving the quality of Lost Foam castings. Porosity and C-rich films Thermal degradation of polystyrene leads to defects. Polystyrene at 400 °C (703 K) Slow (counter-gravity) filling reduces defects
