Formatted Abstract/Summary The CAST Cooperative Research Centre undertakes research on a broad range of light metal topics. CAST's magnesium research covers technologies for the production of magnesium alloys, their casting into billet and shaped castings, subsequent forming (eg extrusion) and post processing (eg corrosion protection, joining and heat treatment). A major strength of CAST and its partners is alloy design where CAST has developed new alloys for creep resistant and structural applications. CAST is a member of the Australian Partnership in Light Metals. Examples of collaboration within the partnership include research on the mechanisms of corrosion undertaken with the ARC Centre of Excellence for Design in Light Metals and on coatings for magnesium applications in high wear and corrosive environments with the CSIRO Light Metals Flagship. The presentation will briefly describe this research.

The presentation will also discuss recent developments in our understanding of grain refinement. Reliable and cost effective grain refinement of Mg-Al alloys is still elusive and CAST has begun a project in collaboration with the CSIRO Light Metals Flagship to address permanent mould casting via their T-Mag casting process. CAST has also developed a new direct chill casting process, AirCAST, where grain refinement is important for reducing hot tearing, improving subsequent extrudability and controlling the final properties of the extruded product.
