The Mechanical Properties of the Superplastic Zn-22Al Alloy at Different Processings

Abstract

To develop a superplastic damper, the mechanical properties of the superplastic Zn-22Al alloy differently processed are studied by the test, at room temperature. It is indicated that the alloy at the air cooling after rolling processing has better mechanical properties at room temperature, such as higher ductility and lower work-hardening, which is very useful to a seismic damper.
