Superplasticity in an Al–Mg–Zr–Sc alloy produced by equal-channel angular pressing

The high-temperature plastic deformation of an Al–4.5 wt.% Mg–0.2 wt.% Zr–0.2 wt.% Sc alloy subjected to equal-channel angular pressing was studied, as well as its microstructure. The alloy exhibits high strain rate superplasticity in the temperature range of 573–798 K. Exceptionally high elongation...
