The influence of artificial aging on the phase composition and the properties of sheets made of V-1213 alloy of Al-Cu-Mg-Ag system. It is shown that the phase composition, morphology, dispersion and the density of phase discharge changes with the temperature increase of artificial aging. After the aging at the highest temperature in the range from 150 to 190 °C the maximum density of S' and Ω' phase is observed. This density provides the best combination of mechanical properties when extended at room temperature and high temperature strengthcharacteristics.
