The Effect of Cu on the Decomposition of Al-Zn-Mg-(Cu) Alloys

Abstract

Lamb J and Sanders Jr. TH

A series of experimental Al-Zn-Mg-(Cu) alloys with a semi-constant Zn:Mg ratio were produced via hot rolling. The effects of Cu in these alloys on the activation energy for precipitation, the response to natural aging, the size of the precipitate free zone, and the corrosion resistance were investigated.
