This study presents the effect of aging on microstructure, texture, mechanical and ballistic properties of AA-7017 aluminium alloy. AA-7017 alloy is subjected to three different aging namely under-aging, peak-aging and over-aging. Significant difference is observed in the mechanical properties after aging. The alloy exhibits maximum strength and ha...

... AA6063 is an aluminum alloy known for its excellent extrudability, moderate strength, good weldability, and resistance to various types of corrosion. Due to these features, the AA6063 alloy finds numerous applications, such as in furniture, doors, architectural extrusions, pipes, window frames, road transport, rail transport, truck, trailer floors, hospital, and medical equipment [6][7][8][9]. ...
... The currents obtained from all samples at the initial application of the anodic potential (−650 mV (Ag/AgCl)) were zero because of the complete coverage of the surface of the samples via a stable film of an oxide that is formed during the exposure to the solution. The current then consciously increases as a result of the dissolution of the surface oxide, and pitting corrosion takes place, as aforementioned, by CPP curves and reactions (4)- (7). Furthermore, the highest absolute currents were obtained for the untreated sample-1, while the sample that was cooled in the furnace (sample-2) presented lower absolute currents. ...
In this work, the AA6063 Al alloy was processed by cooling at four different conditions. The impact of the type of cooling method on the corrosion behavior of the produced alloys after 1 and 24 h in 3.5% NaCl solutions was carried out. Various electrochemical measurements, such as cyclic potentiodynamic polarization (CPP), chronoamperometric, and electrochemical impedance spectroscopy (EIS) measurements, were employed. The CPP data revealed that the intensity of corrosion of the alloys is highly influenced by the cooling method. The change in the chronoamperometric current at −650 mV (Ag/AgCl) over time indicates the possibility of pitting corrosion, particularly after 24 h, where the recorded currents showed a continuous increase over time. The scanning electron microscopy images taken for the surfaces of the alloys after corrosion confirmed that the lowest deterioration occurring on the surface was for the AA6063 alloy that was quenched in water. The EIS plots also demonstrated that AA6063 alloy exhibits different corrosion resistances when different cooling methods are applied. All measurements indicated that the corrosion resistance increases in the following order: the quenched alloy in water > the air-cooled alloy > the furnace-cooled alloy > the as-received alloy. The exposure for 24 h decreases the corrosion damage of all alloys via the formation and thickening of a top layer of corrosion products on its surface over time.
