Technological parameters optimization of the AlZn5Mg3Cu alloy thermomechanical treatment process

Abstract

The paper presents the results of experimental research with a view to optimizing the thermo mechanical treatment process that has been applied to AlZn5Mg3Cu alloy used in the aviation industry. The research led to the conclusion that, for the alloy studied, the highest mechanical strength values were obtained for an artificial aging time of 16 hours at a temperature of 120 °C, while the lowest resistance values were obtained for an artificial aging time of 8 hours at 160 °C.
