Abstract
The effect of temperature on phase composition of cast aluminum alloy containing 0,55 % Zr, 0,23 % Fe and 0,06 % Si has been investigated with the use of Thermo-Calc program for the purpose of support of optimum annealing modes. The phase composition is determined and the equilibrium values of the composition of aluminum solid solution in alloy Al–0,55%Zr–0,23%Fe–0,06%Si are calculated at t = 200÷650 °C. In using multistage annealing, the maximal values of hardness and electric conductivity are shown to be reached at t = 400÷450 °C.
