Friction stir processing (FSP) was applied to extruded Al-Mg-Sc alloy to produce fine-grained microstructure with 2.6 mu m grains. A maximum elongation of 2150% was achieved at 450 degrees C and a high strain rate of 1 x 10(-1) s(-1). Although the grains obtained by FSP were much larger than those by other techniques, such as equal-channel angular pressing, approximately the same superplasticity was achieved at an even higher strain rate in the FSP alloy.
