Abstract

The effect of homogenizing annealing on microstructure and properties of heat-resistant aluminum alloy system of Al-Cu-Mg-Ag is studied. It is established that the increase in temperature of homogenization annealing to 530о C with conducts to reduction of a volume fraction of the second phases with the 12th weight. % to 0,5 weight. %. The interrelation of microstructural changes with the strength and conductive properties is analyzed.
