Effect of heating produced by welding on the microstructure and on the stress corrosion cracking susceptibility of AA7028 alloy
Keywords:Stress corrosion, Welding, Al-Zn-Mg alloys
The microstructural and stress corrosion cracking changes due to welding are studied for the AA7028 aluminium alloy. Special attention is paid to the characterization of what is known as the "white zone". The influence of the delay step between quenching and aging in a T73 treatment on the microstructure and on the characteristics of the heat-affected zone (HAZ) is also studied. Finally, the effect of thermal treatments applied on this zone after the welding is analyzed.
