STRESS CORROSION CRACKING SUSCEPTIBILITY AND AGING CHARACTERISTICS OF AL-ZN-MG-TI ALLOYS

A comparison of the stress corrosion cracking (SCC) susceptibility of four aluminum-zinc-magnesium alloys was determined as a function of processing and composition variables, particularly aging treatment and titanium additions. The SCC tests were performed employing a four point loaded constant moment apparatus in a 3.5% sodium chloride solution at room temperature. The alloys were studied as part of a microstructure and microcomposition characterization program in order to determine the effect of these variables on the SCC susceptibility and mechanical properties of the Al-Zn-Mg system.
