Achieving superplasticity in a Cu-40% Zn alloy through severe plastic deformation

Achieving superplasticity in a Cu-40% Zn alloy through severe plastic deformation
Achieving superplasticity in a Cu-40% Zn alloy through severe plastic deformation
The Cu–40%Zn alloy is a classic two-phase material exhibiting superplasticity at elevated temperatures. This report demonstrates that the application of severe plastic deformation at a temperature associated with a phase transformation leads to grain refinement in the alloy and the development of a superplastic ductility at a high strain rate and relatively low temperature.

Abstract

The Cu–40%Zn alloy is a classic two-phase material exhibiting superplasticity at elevated temperatures. This report demonstrates that the application of severe plastic deformation at a temperature associated with a phase transformation leads to grain refinement in the alloy and the development of a superplastic ductility at a high strain rate and relatively low temperature.
