초록

The ultrafine grained Mg-9.25Zn-1.66Y alloy sheet with I-phase prepared by directly applying high-ratio differential speed rolling to the as-cast microstructure exhibited excellent low-temperature super-plasticity (386-888% at 443-473 K) at a moderately high strain rate of 10(-3) s(-1). A criterion for achieving low temperature superplasticity was proposed. (C) 2015 Elsevier B.V. All rights reserved.
