Abstract

Superplastic aluminium alloys may be divided into two categories: those which recrystallise dynamically during superplastic deformation, such as the Supral alloys (2004 SPF) and 8090 SPF and, secondly those in which the fine grain necessary for superplasticity is produced by static recrystallisation during thermo-mechanical processing.

Both 7475 SPF and 5083 SPF belong to the second category.

This paper describes the superplastic forming characteristics of 5083 SPF and its post-formed mechanical properties.

Some typical applications will be shown to demonstrate the degree of complexity which is possible with this non-heat treatable alloy.
