The Twin-Roll Casting of Magnesium Alloys

Recently, technologies for twin-roll casting have been widely developed to efficiently fabricate the lightweight Mg alloy sheets that art quite attractive for numerous weight-sensitive applications. This paper reviews the recent progress in the twin-roll casting for Mg alloys, focusing on the processing aspects that have close relations to the solidification behavior of Mg alloy strips. In addition, recent attempts to develop new Mg alloys utilizing the metallurgical advantages attainable by this novel casting process are also presented.
