Abstract

The effect of the chemical composition, in particular, of alloying with silver (up to 0.6%) and of the Cu-Mg ratio (from 21.2 to 1.6) in alloys of the Al-(2.4–6.3)% Cu-(0.30–2.0)% Mg system on their mechanical properties is studied. Comparative analysis of the strength characteristics of alloys and of the kinetics of their overaging in tests of pressed semiproducts with a thickness of 10 mm in states T and T1 and after additional heating at a temperature of 180–210°C is performed. Equations characterizing the softening due to the overaging are obtained, which make it possible to compare the properties of alloys under different modes of additional heating.
