• The dynamic SCC behavior of a high strength Al-5% Zn-4% Mg-0.01% Be alloy has been studied in 3.5% NaCl solution using a slow strain rate tensile testing set-up. The influence of the presence of beryllium in trace quantities is most significant in the peak-aged condition and not in the under-aged or over-aged conditions. Through minimizing of grain boundary precipitation, avoidance of PFZ and promoting a more uniform and fine scale precipitation, beryllium brings about a change in the brittle intergranular fracture into transgranular ductile fracture and increases toughness and resistance to dynamic SCC.
