摘要	Friction stir processed Al-Zn-Mg-Cu alloy with grain size 6.2 mu m was subjected to superplastic investigation at 500-535 degrees C and a high strain rate of 1 x 10(-2) s(-1). A maximum elongation of 3250% was achieved at 535 degrees C, which was just above the incipient melting temperature of the sample. Exceptionally high elongation was attributed to the presence of a liquid phase, which served both to relax the stress concentration and to suppress the appearance of cavities during deformation.
