Cladding of Mg alloy with Al has been conducted by simultaneous casting, cladding and rolling a using twin-roll casting process . The as-cast microstructure shows the presence of Mg 17 Al 12 in the reaction zone with good interfacial bonding between the Al and the base Mg alloy. Annealing of the clad sheet results in the additional formation of Mg 2 Al 3 along the Mg/Al interface. Subsequent rolling of the as-annealed sheet reduces the thickness of the reaction zone with a resultant improvement in the formability of the clad sheet.
