Abstract

An investigation was conducted on the superplastic Zn-22% Al alloy to examine the effect of impurity level on mechanical behavior and cavitation in the alloy. In conducting the investigation, three grades of Zn-22% Al containing different levels of impurities (6 ppm, 100 ppm, and 180 ppm) were used. The results show that the deformation behavior of Zn- 22% Al at low stresses is influenced by the impurity level of the alloy, and that the extent of cavitation increases with increasing impurity content. These two findings lend support to the concept of attributing low-stress superplastic deformation to strong impurity segregation at boundaries.
