Superplastic Behavior of Al-Mg-Cu Alloys

A new superplastic Al-Mg-Cu alloy is described. The effect of copper addition on superplastic properties of Al-Mg base alloy (AA5083) has been studied. By addition of 0.6%Cu, a high elongation of about 700% is obtained in deformation at a strain rate of 2.8×10-3s-1 and 550°C. Typical mechanical prop...

Zusammenfassung:	A new superplastic Al-Mg-Cu alloy is described. The effect of copper addition on superplastic properties of Al-Mg base alloy (AA5083) has been studied. By addition of 0.6%Cu, a high elongation of about 700% is obtained in deformation at a strain rate of 2.8×10-3s-1 and 550°C. Typical mechanical properties of formed parts made from the new alloy are 340MPa in tensile strength and 25% in elongation. The present alloy sheet has a potential for general applications in building and construction because of its properties very similar to the conventional 5000 system alloys and high productivity in the conventional casting and rolling process.
