Processing and Elevated Temperature Ductility of Aluminum Alloy 7475

Abstract

This research has initiated investigation of Aluminum alloy 7475 Aluminum-Zinc-Magnesium-Copper in regard to the effects of thermomechanical process (TMP) variables on superplasticity. These effects are evaluated by pct. elongation at temperatures ranging from 300-450 C and strain rates of .0067 to . 000067/s and microstructural analysis. In comparison to results in the literature, superplastic ductility for lower temperature, higher rate superplasticity may be enhanced. Theses. (AW)
