AB  - We have investigated the superplastic deformation mechanism of a powder-metallurgy, high-zinc X7093 Al alloy. The objective was to examine the rate-controlling mechanisms that govern its superplastic deformation. The investigations were carried out in the temperature range 490-524 degrees C and strain rates of 4.17 x 10(-5) s(-1) to 2.1 x 10(-2) s(-1). The maximum ductility was slightly more than 500% at 524 degrees C and 4.2 x 10 s(-1). The values of the stress exponent (n) and the activation energy (Q) indicated that the deformation is rate-controlled by the climb within the grain-boundary diffusion path. The existence of a temperature-dependent threshold stress was confirmed.
