摘要： High strength aluminum alloys based on the Al-Zn-Mg-Cu alloy system preferably include high levels of zinc and copper, but modest levels of magnesium, to provide increased tensile strength without sacrificing toughness. Preferred ranges of the elements include by weight, 8.5-10.5% Zn, 1.4-1.85 % Mg, 2.25-3.0% Cu and at least one element from the group Zr, V, or Hf not exceeding about 0.5%, the balance substantially aluminum and incidental impurities. In addition, small amounts of scandium (0.05-0.30%) are also preferably employed to prevent recrystalization. During formation of the alloys, homogenization, solution heat treating and artificial aging processes are preferably employed.

摘要： High strength aluminum alloys based on the Al-Zn-Mg-Cu alloy system preferably include high levels of zinc and copper to provide increased tensile strength without sacrificing toughness. In addition, small amounts of scandium are also preferably employed 5 to prevent recrystalization. Preferred ranges of the elements include by weight, 8.5-11.0% Zn, 1.8-2.4 % Mg, 1.8-2.6% Cu, 0.05-0.30% Sc and at least one element from the group Zr, V, or Hf not exceeding about 0.5%, the balance substantially aluminum and incidental impurities. During formation of the alloys, a homogenization process is preferably employed after alloy ingot casting in which a slow rate of temperature increase is employed as the alloy is heated as near as possible to its melting temperature. For the last 20-30F below the melting temperature, the rate of increase is limited to 20F/hr. or less to minimize the amount of low melting point eutectic phases and thereby further enhance fracture toughness of the alloy.
摘要翻译：基于Al-Zn-Mg-Cu合金体系的高强度铝合金优选包括高水平的锌和铜，以提供增加的拉伸强度而不牺牲韧性。此外，还优选使用少量的钪5以防止再结晶。元素的优选范围包括8.5-11.0％Zn，1.8-2.4％Mg，1.8-2.6％Cu，0.05-0.30％Sc和至少一种来自Zr，V或Hf族的元素不超过约0.5 ％，余量基本为铝和杂质。在合金形成期间，优选在合金锭铸造之后采用均匀化方法，其中采用缓慢的升温速度，因为合金尽可能靠近其熔融温度被加热。在熔融温度以下的最后20-30°F时，增加速率限制在20F / hr。以下使低熔点共晶相的量最小化，进一步提高合金的断裂韧性。
