“…Specimens that solution treated at 530°C have higher strength than those solution treated at 450°C. This result can be attributed to the combination effect of grain refinement, precipitation and distribution of Mg 2 Si in the grain or at the grain boundaries of the Al [12]. In this case, during solution treatment at higher temperature, more Mg 2 Si particles dissolve in the matrix and the tensile strength will be influenced by cooling.…”

This work examines the effect of solution heat treatment temperature on the tensile strength of Al-Mg-Si aluminum alloy. All samples were machined according to the ASTM B557. The samples were solution treated at 450°C and 530°C and followed by ageing at 160°C for 0, 5, 10, 15 and 20 hours. Tensile test was carried out on the samples after heat treatment. The results showed that the highest tensile strengths (201.69 MPa) was given by the sample solution heat treated at 530 °C for 5 hours followed by 20 hours aging at 160 °C. Whereas, the lowest tensile strength (98.52MPa) was given by the sample solution treated at 450°C for 20 hours. Tensile strength was increased with ageing process and decreased for over-aged samples.

“…Hence the need to strengthen the metal to improve its usefulness. [1] has stated that cold rolling and heat treatment can be used to improve mechanical properties of materials and enhance their performance on application, but an important side effect of these techniques is that they may cause deterioration of the corrosion resistance of the material.…”

6063 aluminium alloy is widely used in architectural applications such as window and door frames because of its nice appearance and acceptable strength. Its major alloying elements are magnesium and silicon. Not many studies focused on the influence of plastic deformation and the alloy content on post-processing quality and corrosion resistance of the alloy have been published. Considering the influence that variation in chemical composition could have on the properties of the alloy, this work aims to investigate the effects of Ferro-Silicon addition, heat-treatment and cold rolling on post-processing quality and corrosion resistance of 6063 Aluminium Alloy. 5000 g of Aluminium 6063 alloyed with 500 g of ferrosilicon was produced. Cast samples from the alloy were homogenized at 350 ºC before cold rolling in the range of 10%, 15%, 20%, 25%, and 30% reduction. The corrosion behaviour of the produced alloy was evaluated using a potentiodynamic test in a 3.5wt % sodium chloride solution. The results show that the addition of FeSi and cold- rolling results in improved mechanical properties but has little effect on corrosion resistance. Heat-treatment has not caused significant impact in corrosion resistance and mechanical properties of the alloy.

AA6063 was heat treated with different retrogression temperatures and durations, and the effect of heat treatment conditions on the microstructure, hardness, electrical conductivity, intergranular corrosion (IGC) and electrochemical corrosion behaviours of the AA6063 was determined compared with the T6 condition. The IGC test was applied according to the BS EN ISO 11846: 2008 standard. Moreover, potentiodynamic polarization tests were applied to determine the electrochemical corrosion behaviour of the heat-treated samples.Electrochemical corrosion tests were carried out by using a Ivium Compactstat potentiostat in 3.5 wt.%. NaCl solution at 24°C with a scanning rate of 0.5 mV/s. The corrosion test cell consisted of the reference electrode (Ag/AgCl), working electrode (test sample) and a reference electrode (platinum). The effect of IGC on the microstructure of AA6063 and corrosion depth values was investigated by using a stereo optical microscope and a light metal microscope, respectively. Corrosion depth examinations were performed on microstructures taken from the cross-sections of the samples. The chemistry of the precipitates formed at grain boundaries and distribution of the precipitates in the microstructure were investigated by scanning electron microscope, energy dispersive X-ray and transmission electron microscope analyses. The results showed that retrogression and reaging heat treatment improves both the corrosion resistance and the mechanical properties of AA6063. After 50°C/15 min RRA heat treatment, the highest corrosion resistance and a higher hardness value than the T6 level were obtained.
