The major disadvantage of light weight alloys like magnesium and aluminum (Al) is the poor formability at room temperature which restricts their wide applications.
However, many researchers [1-4] have shown that forming at elevated temperatures improves the formability of Mg and Al alloys.
A lot of work has been done on the forming of light weight sheets that are made from Al and Mg alloys.
Boumaiza et al [7] studied plastic instabilities of elasto plastic short and long tubes subject to internal pressure.
