- Abstract
- A method for fabricating high-strain-rate superplastic Mg alloys in sheet form by using a high-ratio differential speed rolling process is described. The ingot-metallurgy processed Mg alloy exhibited a superplastic performance comparable to that of powder-metallurgy counterparts. By optimizing the controlling parameters in the rolling process, an ultrafine-grained microstructure with good thermal stability, which is the desired microstructure for achieving high-strain-rate superplasticity, could be obtained using only a few processing steps.
