Exploring the effects of specific alloying elements on the production, extrusion and properties of 6xxx series aluminium alloys
主讲人 : Prof. Malcolm James COUPER
The optimisation of 6xxx series aluminium alloy compositions has evolved via empirical studies of heat-treated properties, followed by investigations into the effect of homogenisation on extrudability and properties. This optimisation has also been influenced by the imperatives of cost, market competition and certification. To illustrate the inherent trade-off between productivity and properties, some examples will be selected from the major elements Mg, Si and Cu, minor elements Fe, Mn and Cr and trace elements Na, Ti, etc in 6xxx series alloys. The development of advanced microscopy and modelling techniques has led to resurgence in attempts to further improve aluminium alloys. Some comments will be made on the future development of 6xxx alloys.
Prof. Couper is currently based in Materials Science & Engineering at Monash University in Australia. After completing a Ph.D. at Monash, he worked within industry R&D with Asea Brown Boveri (ABB) and Rio Tinto Aluminium (formerly Comalco), covering many aspects of aluminium production processes, products and manufacturing. Other activities during this time included Technical Advisor to the Collaborative Research Centre, CAST (1993-2012); Adjunct Professor at the University of Queensland (2001-12) and past-director and president of the Institute of Materials Engineering Australasia. He returned to Monash as research coordinator for the Centre of Excellence in Design of Light Metals, Australia (2010-11) and undertakes some teaching at Monash and CSU. Research interests have included rapid solidification and powder metallurgy; fatigue properties; metal matrix composites; foundry castings processes and heat-treatment; wrought alloy development; microstructural characterization, properties and alloy design.
