Developing high strain rate superplasticity in Al-Mg-Sc-Zr alloys using equal-channel angular pressing

The processing of metallic alloys through the procedure of equal-channel angular pressing (ECAP) provides an opportunity for achieving superplastic ductilities at very high strain rates. This paper reports experimental data from an investigation of a series of Al---Mg---Sc---Zr alloys processed by ECAP. The results show the occurrence of high tensile ductilities at testing strain rates above 10?2 s?1. <br/
