Определен фазовый состав и рассчитаны равновесные значения состава алюминиевого твердого раствора в сплаве Al–0,55%Zr–0,23%Fe–0,06%Si при t = 200÷650 °С. Показано, что при использовании многоступенчатого отжига максимальные значения твердости и электропроводности достигаются при t = 400÷450 °С</p></abstract><trans-abstract xml:lang="en"><p>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.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>алюминиевые сплавы</kwd><kwd>термическая обработка</kwd><kwd>электропроводность</kwd><kwd>фазовый состав</kwd></kwd-group><kwd-group xml:lang="en"><kwd>aluminum alloys</kwd><kwd>heat treatment</kwd><kwd>electric conductivity</kwd><kwd>phase composition</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Энтони У.У., Элиот Ф.Р., Болл М.Д.
