“…This prediction model uses the alloy's chemical composition, parameters of the tempers, and Brinell hardness as input parameters. Similarly, Sigli et al (1996) developed a prediction model within a metallurgical simulator to estimate yield strength based on process parameters. Their model takes into account factors such as microstructure, cold rolling reduction, baking time, and temperature.…”

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.
