DESCRIPTION:for Sc and Zr Containing Al-Mg-Si Alloys\n\nMaterials Science a
 nd Engineering Seminar\n\nDr. Steven Babaniaris\n\nInstitute for Frontier M
 aterials\nDeakin University\nWaurn Ponds\, Australia\n\nAbstract: Light-wei
 ghting of vehicles drives the development of Aluminium alloys with improved
  strength\, processablity and formability. An opportunity to achieve these 
 goal is using Scandium (Sc). The beneficial effects from Sc comes from the 
 formation of nano-sized Al3Sc dispersoids. Detrimental interactions between
  Sc and Silicon (Si)\, coupled with the high price of Sc has limited the re
 search and uptake of Sc in 6xxx alloys. The first step towards developing S
 c containing 6xxx-series is to understand the as-cast microstructure and th
 e effect of subsequent heat treatment on the dispersoids and precipitates.\
 n\nThis work uses isochronal ageing trials on a series of Al-Mg-Si-(Sc)-(Zr
 ) model alloys. The evolution of hardness and conductivity is recorded to i
 ndirectly characterise the precipitate sequence in these alloys. TEM\, APT 
 and DSC are also used to further characterise the morphology and kinetics o
 f MgSi precipitates and Sc/Zr dispersoids. The precipitation of Sc was alte
 red by the presence of Si\, and hence it is concluded that a non-traditiona
 l homogenisation treatment will be required for these alloys.\n\nBio: Dr Ba
 baniaris recently completed his PhD at the Institute for Frontier Materials
  (IFM)\, Deakin University under the supervision of Prof. Matthew Barnett a
 nd Dr Aiden Beer. His PhD thesis focused on understanding the microstructur
 al and optical origins of thermomechanical streaking defects\, a known issu
 e in the production of anodized architectural aluminium extrusions.\n\nDr B
 abaniaris now works as a postdoctoral research fellow at the IFM where mana
 ges and operates Deskins 300 ton research dedicated extrusion facility. His
  current research focus is on the development and processing of advanced ag
 e hardenable aluminium extrusion alloys containing scandium.
