“…Al-Mg-Si-Cu (6000 series) alloy sheets are widely used in manufacturing engineering products such as automotive structures, shipping containers and various domestic appliances, due to their good combination of high specific strength, high ductility, high corrosion resistance and low production cost [1][2][3][4][5]. The addition of 0.6% Cu can induce the dense precipitation of Q (AlMgSiCu) phase in addition to β (Mg 2 Si), which can significantly improve the age hardening rate of the alloy by 25% [6,7].…”

Surface treatment has shown strong effects on the corrosion resistance of Al-Mg-Si-Cu alloys. To elucidate the surface grinding effects, a set of the peak-aged Al-Mg-Si-Cu samples are ground using SiC papers with different grits, and the ground surface microstructure and corrosion performance are investigated. The results show that grinding generates a deformed near-surface layer. The deformed layer is characterized by nanocrystalline and the alloying element Cu segregates at nano-grained boundaries. The Cu segregation bands increase the available cathode area and the potential difference between the grain boundary and grain interior, which enhances the microgalvanic corrosion effect between the phase α-AlFeSi (Mn, Cu) and the adjacent matrix. As the SiC paper grit number decreased from 1200 to 80, the Cu segregation bands of the deformed layers increases from 600 to 1600 nm, the corresponding corrosion current density increases from 1.0 ± 0.1 to 22.8 ± 0.7 μA.cm−2, and the corrosion potential decreases from −742 ± 13.1 to −791 ± 15.0 mV (versus SCE).

“…Alloy 6013 is finding increasing usage in aerospace applications and automotive industry due to the low cost and beneficial properties such as medium strength, good weldability, corrosion resistance and immunity to stress-corrosion cracking [1][2][3][4][5]. Alloy 6013 is an aluminum-magnesium-silicon-copper alloy that has 25% higher strength than the 6061 alloy and it is weldable.…”

The effect of enhanced solution treatment on microstructures, tensile properties, intergranular corrosion and exfoliation corrosion of a 6013 type aluminum alloy proceeded via various solution treatment were investigated by optical microscopy (OM), scanning electron microscopy (SEM), tension testing and corrosion resistance testing. The results show that compared with the conventional solution treatment (560°C×2 h), the enhanced solution treatment (560°C×2 h+570°C×2 h) can improve ultimate tensile strength and elongation, the corrosion resistance become worse after 151°C×8 h+191°C×8 h artificial aging. The tensile strength increase is believed to resulting from the coarse second phases dissolve. The corrosion resistance decrease is due to grain growth.
