The influence of strain rate on ductility in the superplastic Zn-22% A1 eutectoid

The influence of strain rate on ductility in the superplastic Zn-22% A1 eutectoid
The influence of strain rate on ductility in the superplastic Zn-22% A1 eutectoid
There is an optimum range of strain rate for maximum ductility in the superplastic Zn–22% Al eutectoid, and the elongation at fracture decreases at both low and high strain rates. For a testing temperature of 473 K and a grain size of 2·5 μm, tensile specimens deform to strains in excess of 2000% over almost two orders of magnitude of strain rate.

Abstract

There is an optimum range of strain rate for maximum ductility in the superplastic Zn–22% Al eutectoid, and the elongation at fracture decreases at both low and high strain rates. For a testing temperature of 473 K and a grain size of 2·5 μm, tensile specimens deform to strains in excess of 2000% over almost two orders of magnitude of strain rate.
