Strategies for achieving high strain rate superplasticity in magnesium alloys processed by equal-channel angular pressing
Magnesium alloys processed by equal-channel angular pressing often exhibit superplastic elongations at low strain rates. Two strategies are available for achieving high strain rate superplasticity: (i) by pressing the alloys through a reduced number of passes in order to increase the thermal stability of the microstructure; and (ii) by increasing the processing temperature to permit the occurrence of superplastic flow at higher testing temperatures.

Abstract

Magnesium alloys processed by equal-channel angular pressing often exhibit superplastic elongations at low strain rates. Two strategies are available for achieving high strain rate superplasticity: (i) by pressing the alloys through a reduced number of passes in order to increase the thermal stability of the microstructure; and (ii) by increasing the processing temperature to permit the occurrence of superplastic flow at higher testing temperatures.
