摘要

The effect of temperature and duration of artificial aging on the strength and ductility characteristics of aluminum alloy 2219-T87 was investigated in static tensile tests of a 6 mmthick plate. It was found that the tensile strength of the alloy after aging decreases, and the yield strength increases significantly as a result of the precipitation hardening process. At the same time, an increase in the artificial aging temperature leads to more significant changes in the strength characteristics of the alloy, as well as to a decrease in its ductility. It is shown that in order to achieve the optimal ratio of mechanical characteristics of alloy 2219-T87 in each specific case, an individual approach to the assignment of the artificial aging mode is necessary.
