Description
Изобретение относитс к области цветной металлургии, к разработке высокопрочных и легких конструкционных материалов.The invention relates to the field of non-ferrous metallurgy, to the development of high-strength and light structural materials.
Известные сплавы системы А1-Си-Мп- Ti-Cd-Zr обладают недостаточно высокими прочностными и пластическими характеристиками , особенно при литье в землю.Known alloys of the A1-Cu-Mn-Ti-Cd-Zr system do not have sufficiently high strength and plastic characteristics, especially when cast into the ground.
Отличительной особенностью разработанного сплава вл етс найденное оптимальное соотношение компонентов в системе А1-Си- Мп--Ti-Cd-Zr при дополнительном легировании сплава кремнием и бором, что обеспечивает повышение литейных свойств материала и его прочности.A distinctive feature of the developed alloy is the found optimum ratio of components in the A1-Cu-Mn-Ti-Cd-Zr system with additional alloying of the alloy with silicon and boron, which improves the casting properties of the material and its strength.

В соответствии с химическим составом рекомендуетс следуюш,ий режим термнческой обработки; нагрев до температуры 515±5°С, выдержка до 6 час, далее повышение температуры до 545±5°С и выдержка до 12 час, после чего охланаденне в воде при 20-100°С.According to the chemical composition, the following thermal treatment mode is recommended; heating to a temperature of 515 ± 5 ° С, holding up to 6 hours, then raising the temperature to 545 ± 5 ° С and holding up to 12 hours, after which it is cooled in water at 20-100 ° С.
После закалки следует искусственное старение при 175±10°С с выдержкой 3-8 час. Термическа обработка по режиму Т5 обеспечивает получение на отдельно отлитых образцах следуюш,их механических свойств.After quenching, artificial aging follows at 175 ± 10 ° С with a holding time of 3-8 hours. Thermal treatment in T5 mode provides for obtaining on their separately cast samples their mechanical properties.
