Abstract
High strain-rate superplasticity was obtained in the mechanically alloyed aluminum IN905XL alloy. Introducing a threshold stress into the rate equation, the true values of n and Q established. It is postulated that superplastic flow in the IN905XL alloy is controlled by a grain boundary sliding mechanism accommodated by dislocation climb or glide controlled by grain boundary diffusion.
