Definitions

  • This invention relates to the field of metallurgy, in particular to high strength weldable alloys with low density, of aluminium-copper-lithium system, said invention can be used in air- and spacecraft engineering.
  • the aluminium-based alloy comprising (mass %): copper 2.6-3.3 lithium 1.8-2.3 zirconium 0.09-0.14 magnesium ⁇ 0.1 manganese ⁇ 0.1 chromium ⁇ 0.05 nickel ⁇ 0.003 cerium ⁇ 0.005 titanium ⁇ 0.02-0.06 silicon ⁇ 0.1 iron ⁇ 0.15 beryllium 0.008-0.1 aluminium balance (OST 1-90048-77)
  • the disadvantage of this alloy is its low weldability, reduced resistance to impact loading and low stability of mechanical properties in case of prolonged low-temperature heating.
  • the aluminium-based alloy with the following composition has been chosen as a prototype: (mass %) copper 1.4-6.0 lithium 1.0-4.0 zirconium 0.02-0.3 titanium 0.01-0.15 boron 0.0002-0.07 cerium 0.005-0.15 iron 0.03-0.25 at least one element from the group including: neodymium 0.0002-0.1 scandium 0.01-0.35 vanadium 0.01-0.15 manganese 0.05-0.6 magnesium 0.6-2.0 aluminium balance (RU patent 1584414, C22C21/12, 1988)
  • the disadvantage of this alloy is its reduced thermal stability, not high enough crack resistance, high anisotropy of properties, especially of elongation.
  • the shortcoming of this method is the low thermal stability of semiproducts' properties because of the residual supersaturation of the solid solution and its subsequent decomposition with precipitation of fine particles of hardening phases, and also the low elongation and crack resistance, all of which increases the danger of fracture in the course of service life.
  • the disadvantage of this method is the wide range of mechanical properties' values due to wide interval of deformation temperatures and low thermal stability because of the residual supersaturation of solid solution after ageing.
  • the suggested aluminium-based alloy comprises (mass %): copper 3.0-3.5 lithium 1.5-1.8 zirconium 0.05-0.12 scandium 0.06-0.12 silicon 0.02-0.15 iron 0.02-0.2 beryllium 0.0001-0.02 at least one element from the group including magnesium 0.1-0.6 zinc 0.01-1.0 manganese 0.05-0.5 germanium 0.02-0.2 cerium 0.05-0.2 yttrium 0.005-0.02 titanium 0.005-0.05 aluminium balance
  • the Cu/Li ratio is in the range 1.9-2.3.
  • the suggested method differs from the prototype in that the billet prior to deformation process, is heated to 460-500° C., the deformation temperature is not less than 400° C., and the artificial ageing process is performed in three stages: first at 155-165° C. for 10-12 hours, then at 180-190° C. for 2-5 hours and lastly at 155-165° C. for 8-10 hours; then is performed cooling to 90-100° C. with cooling rate of 2-5° C./hour and subsequent air cooling to room temperature.
  • the task of the present invention is the weight reduction of aircraft structures, the increase in their reliability and service life.
  • the technical result of the invention is the increase in plasticity, crack resistance, including the impact loading resistance, and also the increase in stability of mechanical properties in case of prolonged low-temperature heating.
  • the suggested composition of the alloy and the method of fabrication of semiproducts from said alloy ensure the necessary and sufficient saturation of the solid solution, allowing to achieve the high hardening effect at the expense of mainly fine T 1 -phase (Al 2 CuLi) precipitates without residual supersaturation of the solid solution with Li, and that results in practically complete thermal stability of the alloy in case of prolonged low—temperature heating.
