Definitions

  • the invention relates to alloys based on Al of the 7000 series, according to the nomenclature of Aluminum Association (AA), having a high Young modulus and high mechanical characteristics of resistance and toughness as well as their method of obtaining.
  • AA Aluminum Association
  • the most resistant Aluminum alloys of the 7000 series generally have a Young E modulus of the order of 70 GPa but not exceeding 72-73 GPa.
  • alloys based on Al containing Li Admittedly, alloys based on Al containing Li are known, the elastic modulus and mechanical characteristics of which are high. However, these pose complex production problems, given the reactivity of the Li and this therefore requires special and costly production and casting installations.
  • the alloys according to the invention can be produced using conventional installations known in the metallurgy of common Al alloys. In addition, the mechanical resistance characteristics of Al-Li are generally lower than those of 7000 alloys.
  • Alloys of type 7000 much more loaded with alloying elements and obtained by powder metallurgy have high mechanical characteristics, good resistance to corrosion under tension but a modulus less than 74 GPa.
  • the invention therefore relates to the alloys with the following weight composition (in%) Zn: 5.5 - 8.45 Mg: 2.0 - 3.5 Cu: 0.5 - 2.5 Zr: 0.1 - 0.5 Cr: 0.3 - 0.8 Mn: 0.3 - 1.1 Fe: up to 0.5 If: up to 0.5 other items each ⁇ 0.05 total ⁇ 9.15 Rest Al
  • a preferred composition is as follows: Zn: 7.0 - 8.4 Mg: 2.0 - 2.9 Cu: 0.8 - 2.0 Zr: 0.1 - 0.4 Cr: 0.3 - 0.6 Mn: 0.3 - 0.9 the rest being identical to the above compositions.
  • spray-deposition is meant a process in which the metal is melted, atomized by a jet of gas at high pressure in the form of fine liquid droplets which are then directed and agglomerated on a substrate so as to form a massive and coherent deposit, containing low closed porosity.
  • This deposit can be in the form of billets, tubes or plates whose geometry is controlled.
  • the hot transformation stage may be preceded by a homogenization treatment of the solid body, in one or more stages, between the temperatures of 450 and 520 ° C., generally between 2 and 50 hours.
  • the product thus obtained meets the characteristics referred to above. These properties are attributed to a fine dispersion of standard phases (Al, Mn, Cr) and Al3Zr - due to the combination of the composition of the alloy and to its production process; this structure makes it possible to achieve, among other things, good ductility, toughness and a high elastic limit.
  • the dissolution is generally carried out between 450 and 520 ° C and the T6 type treatment between 90 and 150 ° C, for a sufficient time to substantially obtain the hardness peak (from 2 to 25 hours).
  • the T7 treatment consists of a T6 type treatment supplemented by tempering at a higher temperature, for example between 150 and 170 ° C, for 0.5 to 20 hours.
  • the invention is also applicable to composite materials hardened by dispersed ceramic particles of the oxide, carbide, nitride, silicide, boride, etc. type introduced into the alloy according to the invention, which constitutes the matrix thereof, during operation 1 , for example by injecting the powder into the liquid stream. These particles have a size between 1 and 50 ⁇ m and represent (relative to the metal) a volume fraction of between 3 and 12%.
  • alloys 1 to 4 are in accordance with the invention, alloys 5 and 6 are outside the invention and alloy 7 is a conventional alloy (7075) from the prior art for comparison; this was poured semi-continuously and processed hot and heat treated like the other alloys; FIG. 1 represents the mechanical characteristics E and R 0.2 of the alloys tested, FIG. 2 the characteristics of toughness as a function of R 0.2 and FIG. 3 the characteristics of corrosion under tension as a function of R 0.2 .
  • the billets are homogenized for 8 hours at a temperature of 460 ° C.
  • the blanks are then hot-spun at 400 ° C in a press whose container has a diameter of 143 mm in the form of flats of section 50 x 22 mm, ie a spinning ratio of 14.6.
  • the flats thus obtained undergo a T7 type heat treatment under the following conditions: - solution for 2 hours at a temperature between 460 and 485 ° C - cold water quenching - two-bearing income: 24 hours at 120 ° C + 1 to 20 hours between 155 and 170 ° C
  • Alloys 1 to 4 are in the claimed field and have a module ⁇ 74 GPa and a long-term elastic limit ⁇ 530 MPa while having good long-term ductility ( ⁇ 8%) and long cross-beam ( ⁇ 6%), a toughness LT direction of at least 20 MPa ⁇ m and good resistance to corrosion under tension (measured according to standard ASTM G 38 73).
  • the alloy 5 is outside the invention because of its too high Cr and Mn content, and although having a high modulus and elastic limit, it is very little ductile and cannot be used for the manufacture of parts.
  • the alloy 6 is also outside the invention because of its too low Cr and Mn content, does not have the advantages of the alloys according to the invention, has a low modulus and elastic limit and therefore does not differ from the alloys classics like the 7075.
  • composition and properties of a conventional 7075 alloy conventionally cast and then transformed and heat treated according to the same range as the alloys 1 to 6 are reported for comparison.
  • the alloys according to the invention are mainly intended for the manufacture of profiles or parts of forged or stamped structures.
