Abstract
Abstract It is well known that Equal-Channel Angular Pressing (ECAP) introduces an ultrafine grain size and leads to exceptional superplastic properties in a ZK60 (Mg-5.5 % Zn-0.5 % Zr) alloy. This paper presents an analysis of the flow behavior during superplastic deformation in the ZK60 alloy. It is shown that an increase in the ECAP processing temperature enhances the thermal stability of the grain structure. In addition, the optimum superplastic properties occur at higher strain rates when testing at higher temperatures thereby introducing the potential for achieving high strain-rate superplasticity.
