Abstract
The effect of the content of silver in the amount of 0.6 wt.% and of the Cu/Mg ratio in the range of 1.6 – 15 on the temperature ranges of phase transformations and on the properties of alloys of the Al - Cu - Mg - Ag system is studied with the aim of amending heat treatment modes. Pressed strips with cross section 10 × 100 mm are studied after natural and artificial aging. The method of differential scanning calorimetry is used to determine the temperature ranges and thermal effects in solid-phase dissolution (segregation) of excess phases and melting of the structural components. Mechanical properties are determined at room and elevated temperatures and the microstructure over the cross section of the strips is studied.
