Interfacial intermetallic compound (IMC) layer is critical during realizing the galvanic corrosion mechanism and strength degradation of aluminium/steel resistance spot welding (RSW) joints. The effect of IMC layer on the corrosion behaviour of RSW joint between 5182 aluminium alloy and galvanized DP780 dual-phase steel was investigated by immersion corrosion method and electrochemical method. Results demonstrated localized corrosion around Fe-rich phase particles on aluminium nugget and preferential corrosion at the interface front near IMC layer. The IMC layer had the highest open circuit potential value of -0.569 V and low corrosion current density among the investigated nugget and substrates. The potential difference (0.184 V) between the cathodic IMC layer and large area of anodic aluminium nugget was responsible for the preferential initiation of localized corrosion at the interface front near the IMC layer.

High-performance extruded aluminum alloys with complex textures suffer significant dimension variation under environmental temperature fluctuations, dramatically decreasing the precision of navigation systems. This research mainly focuses on the effect of the texture of extruded pure aluminum on its dimensional stability after various annealing processes. The result reveals that a significant increment in the area fraction of recrystallized grains with <100> orientation and a decrement in the area fraction of grains with <111> orientation were found with increasing annealing temperature. Moreover, with the annealing temperature increasing from 150 °C to 400 °C, the residual plastic strain after twelve thermal cycles with a temperature range of 120 °C was changed from −1.6 × 10−5 to −4.5 × 10−5. The large amount of equiaxed grains with <100> orientation was formed in the microstructure of the extruded pure aluminum and the average grain size was decreased during thermal cycling. The area fraction of grain with <100> crystallographic orientation of the sample annealed at 400 °C after thermal cycling was 30.9% higher than annealed at 350 °C (23.7%) or at 150 °C (18.7%). It is attributed to the increase in the proportion of recrystallization grains with <100> direction as the annealing temperature increases, provided more nucleation sites for the formation of fine equiaxed grains with <100> orientation. The main orientation of the texture was rotated from parallel to <111> to parallel to <100> after thermal cycling. The change in the orientation of grains contributed to a change in interplanar spacing, which explains the change in the dimension along the extrusion direction during thermal cycling.

The paper examines the influence of aging on buckling strength loss for aluminum alloy 5182 beverage can ends. In the experimental study, aging took place naturally and artificially. For the buckling strength testing, a special experimental technique was used, which was based on measuring the internal pressure leading to the destruction of the beverage can ends. The experimental results show that the beverage can ends indicate a significant time-dependent buckle strength loss. For example, a year of aging can end at 20°C leading to a decrease in its strength by 5%. Half of this decrease occurs in the first 3-4 weeks. The aging phenomenon also got worse with increasing temperature. It has been found that increasing the aging temperature to 40°C results in an 8% reduction in buckling strength after 4 weeks of aging. The whole life cycle, from its production to the processes it undergoes and storage time, was analyzed. At the same time, tests were carried out for both the input material and the product itself. On this basis, the mechanical properties and their change depending on time or temperature were examined. All specimens made from can end stock (CES) were also found to not show the same drop of mechanical properties as for the buckling of finished ends. The obtained experimental allowed the development of an empirical mathematical model that makes it possible to predict the buckling strength of the can end depending on the conditions of aging and temperature of testing. The present study showed the importance of temperature conditions used in can filling lines in the determination of resistance to changes in buckling for the ends.
