Abstract
A new superplastic Al-Mg-high Mn alloy called a high-Mn alloy in the present paper was
developed. The superplastic properties of the high-Mn alloy were evaluated in comparison with a
conventional superplastic 5083 alloy which was manufactured under the same industrial mass
production process. The high-Mn alloy sheet of a middle thickness shows a lager elongation to failure
at temperatures below 783K, and show better superplastic formability and less cavitation volume than
the 5083 alloy. These superior characters of the high-Mn alloy may be ascribable to finer grain
structure formed in the alloy.
