Quantitative study of superplastic deformation mechanism of 5A90 Al-Li alloy

The contribution of grain boundary sliding(GBS) and intragranular dislocation slip(IDS) in the 5A90 Al-Li alloy during superplastic deformation at 480℃ and an initial strain rate of 1×10<sup>-3</sup>s<sup>-1</sup> was quantitatively investigated by analyzing the deformation-i...
