Abstract

Differential scanning calorimetry (DSC) and transmission electron microscopy (TEM) have been used to examine the precipitation process in spray cast Al - Zn - Mg - Cu alloys. The study was carried out on an Al - 5-6Zn 2-5Mg-1.6Cu alloy and an Al-11-5Zn-2-64Mg-1-16Cu alloy (wt-%). The effect of zinc on the precipitation process in the alloys was investigated. It was found that additional zinc accelerated the kinetics of formation of the precipitates.
