Title

High Strain Rate Superplasticity in a Commercial 2024 Al Alloy via Friction Stir Processing

Abstract

A novel technique for producing high-strain-rate-superplastic (HSRS) microstructure via friction stir processing (FSP) in a commercial 2024 Al has been demonstrated. A maximum ductility of 525% has been achieved at a strain rate of 10−2 s−1 and 430 °C. Current results suggest that friction stir processing can be developed as a simple yet effective technique for producing microstructure amenable for superplasticity at high strain rates and/or lower temperatures and at lower flow stresses.
