  • the invention relates to an aluminum-based alloy, preferably of the Al-Li-Mg system, which contains lithium, magnesium, zinc, zirconium and manganese and is in the field of metallurgy of alloys which are used as materials for constructions in aerospace engineering, used in shipbuilding and mechanical engineering of ground-based means of transport, including welded structures.
  • Alloys of the Al-Li-Mg system which have a reduced density and a relatively high strength, but have a low ver orbarability and reduced fracture toughness.
  • the alloy according to US Pat. No. 4,584, 173 dated April 22, 1986 has, for example, the following chemical composition, in percent by mass:
  • Germanium 0-0.2 If this alloy is quenched at a temperature of 530 ° C and then subjected to stretch straightening with a degree of deformation of 2% and an artificial aging at 190 ° C for 4 to 16 hours, the disadvantage arises that the alloy has low plasticity in heat-treated condition (relative elongation 3J - 4.5%) and has low corrosion resistance.
  • the alloy according to international patent application WO No. 92/03583 has the following chemical composition in mass percent:
  • the alloy can contain up to 1.0% zirconium.
  • This alloy has a strength of 476-497 MPa, a yield strength of 368-455 MPa, a relative elongation of 7-9% and a density of 2.46-2.63 g / cm 3 .
  • the alloy is recommended as a structural material for products in the aerospace industry.
  • the disadvantages of this alloy are as follows:
  • the high strength can be guaranteed:
  • Sheets used for aircraft due to a high zinc content; this increases the density of the alloy to values of 2.60-2.63 g / cm 3 , which significantly reduces the weight-saving effect of the product;
  • the alloy is alloyed with silver, which increases product costs - from semi-finished products to finished products. Alloys with a high zinc content and added copper show a reduced
  • the alloy is hardened by heat treatment: quenching from a temperature of 460 ° C, stretching with a degree of stretching of 0 - 3% and a two-stage heat treatment: the 1st stage at 90 ° C, 16 h and the 2nd stage at 150 ° C , 24 hours.
  • This alloy has a sufficiently high strength level of 440 - 550 MPa and a yield strength of 350 - 410 MPa.
  • the disadvantages of this alloy are the low level of relative elongation of the alloy (1.0 - 7.0%) and the low fracture toughness, insufficient corrosion resistance and the limited strength of welded joints compared to the strength of the base material.
  • the object of the present invention is therefore to achieve an increase in the ductility of the alloy in the heat-treated state while maintaining high strength and ensuring high corrosion resistance and good weldability, with sufficiently high characteristic values for the fracture toughness and the thermal stability after heating at 85 ° C should be guaranteed within 1000 h.
  • the hydrogen content with the formation of solid, finely divided particles of lithium hydride, reduces the longitudinal shrinkage during solidification and prevents the formation of porosity in the material.
  • the magnesium content ensures the necessary level of strength properties and weldability. If the magnesium content is reduced below 4J% reduce strength and increase the tendency of the alloy to hot cracks in both casting and welding. If the magnesium content of the alloy is increased by more than 6.0%, the machinability during casting, hot and cold rolling and the plasticity characteristics of finished semi-finished products and products thereof are reduced.
  • Compliance with the lithium content is essential to ensure the necessary machinability, particularly in the production of thin sheets, the necessary level of mechanical and corrosion properties, and sufficient fracture toughness and weldability.
  • the lithium content With a reduction in the lithium content below 1.5%, the density of the alloy increased, the level of strength properties and the modulus of elasticity decreased, with a lithium content above 1.9%, the machinability by cold working, the weldability, the plasticity values and the fracture toughness deteriorated.
  • Zirconium in the amount of 0.05 - 0.3% is a modifier when casting ingots and, together with the manganese (in the amount of 0.01 - 0.8%), ensures structural solidification in the semi-finished products as a result of the formation a polygonized or fine-grained structure.
  • the formation of a homogeneous fine-grained structure in semi-finished products made from the alloy according to the invention increases the deformability during cold rolling.
  • the invention further relates to a method for the heat treatment of aluminum-based alloys, preferably the Al-Li-Mg system.
  • the task of such a heat treatment process is to increase the ductility of the alloy while maintaining its high strength and at the same time to achieve high values for corrosion resistance and fracture toughness, but in particular that Preservation of these properties when the material is exposed to elevated temperatures over a long period of time.
  • a heat treatment method is known from US Pat. No. 4,861,391, which comprises quenching with rapid cooling, straightening and two-stage aging as follows:
  • the 1st stage at a temperature not above 93 ° C, from a few hours to a few
  • Months preferably, 66 - 85 ° C, at least 24 h.
  • the second stage at a maximum temperature of 219 ° C, from 30 minutes to a few hours; preferably, 154 - 199 ° C, maximum 8 h.
  • a method for solving the task comprises the method steps
  • alloys according to the invention with the feature of claim 1 have particularly advantageous properties in the sense of the task if they were treated by the aforementioned method.
  • these heat treatment processes ensure the thermal stability of the alloys after long low-temperature aging due to the additional precipitation of the disperse phase ⁇ '- (Al3Li), which is evenly distributed in the matrix volume.
  • the large volume of the finely divided ⁇ '-phase reduces the Li supersaturation of the mixed crystal and prevents ⁇ '-excretion during aging at 85 ° C, 1000 h.
  • the first stage of artificial aging takes place at a temperature of 80-90 ° C in the course of 3-12 h and a second stage at 110-105 ° C in the course of 10 - 48 h.
