Abstract
The influence of small addition of Sc on the superplastic potential of Al–Zn–Mg–Cu–Zr alloy AA 7010 has been examined. The alloy was subjected to a three-step thermo-mechanical process (TMP) and the resultant material (having essentially an unrecrystallized grain structure) was subjected to a strain rate–temperature combination of 1.9 × 10−2 s−1, 475 °C to develop recrystallized grain structure amenable to superplastic deformation. This resulted in a total elongation of 650%.
