Biswas , P K and Dev, S C and Krishnan, C S S (1998) Some Critical Issues in the Processing of Magnesium Alloys & Composites. In: UNSPECIFIED.
Handling of molten Mg alloys and composite slurries is risky due to the danger of explosion and oxidation in contact with O, of the atmosphere and water. Hence special attention is to be taken for safety and quality in all steps of processingmelting.moulding. casting, heat treatment and mechanical working. The limitations and specialities are in respect of alloying (viz.with Zr.Mn-Ca_Be), removal of nonmetallic and metallic impurities (viz.Fc.Ni etc), grain refinement. degassing. choice of flues and the mariner of its addition. die design for extrusion. selection of temperature and time in melting. pouring and heat treatment- selection of stirrer rpm- its geometry and location in the bath for composite making by stir casting including nccocasting methods etc. These issues are revieNwd in this paper.
