Abstract

Superplastic ductilities were achieved in a dilute magnesium alloy containing 0.6% Zr through the use of a two-step processing procedure in which the basal planes are initially aligned through extrusion and the grain size is then refined using equal-channel angular pressing. The results show a maximum tensile elongation of >400% at 573 K when using an initial strain rate of 3.3×10?4 s?1.
