Technical Note:Stress Corrosion Cracking Behavior of Two High-Strength Al-xCu-Li-Ag-Mg-Zr Alloys

Determination of true stress corrosion cracking susceptibility index of a high strength Al alloy using glycerin as the non-corrosive atmosphere

“…Considering the laboratory air to be a non-corrosive medium, the SCC susceptibility of Al alloys is usually assessed by comparing the mechanical properties of the alloy obtained in 3.5% NaCl solution to those obtained in laboratory air [4][5][6][7]. However, our recent study [8] on the SCC behavior of 7010 Al alloy has shown that the ductility of the alloy in peak aged and over aged conditions decreased as the strain rate was decreased from 10 À5 /s to 10…”
