In-situ surface study on the mechanism of high-strain-rate superplasticity in an Al–Cu–Li alloy
An elongation of 880 % was obtained at a high initial strain rate of 1 × 10−2 s−1 at 470 °C in an Al–Cu–Li alloy produced by traditional thermomechanical-processing. The high-strain-rate superplastic deformation mechanisms during the whole deformation process were studied by SEM, EBSD, and FIB techn...
