Processing by equal-channel angular pressing (ECAP) leads to exceptional grain refinement, typically to the submicrometer or nanometer level. If these small grain sizes are stable at elevated temperatures, there is a potential for achieving superplastic ductilities at very rapid strain rates. This paper examines the requirements for achieving high strain rate superplasticity in as-pressed materials and gives examples demonstrating the success of this processing method.
