Abstract

The correlation between chemical composition, multiphase microstructure and stress corrosion performance of Al–Zn–Mg alloy with different thickness coarse grain layers was studied by optical microscopy (OM), scanning electron microscope (SEM), transmission electron microscopy (TEM), tensile test and four point bending stress corrosion performance test. The results indicated that the thickness of coarse grain layer of three kinds of Al–Zn–Mg alloy profiles used in the test were about 200, 400 and 900 μm, while the stress corrosion cracking (SCC) resistance and strength of specimens with coarse grain layer decreased with increase of coarse grain layer thickness. Among different profiles, the stress corrosion cracking resistance of specimens with coarse grain layer and center layer without coarse grain layer exhibited the difference with the change of coarse grain thickness.
