Definitions

  • the invention relates to Al-based alloys with high heat stability.
  • Alloys based on A1 are known which exhibit good hot stability, in particular those described in French patent application FR 2 190 553 or US patent 4 347 076.
  • alloys based are described. of Al containing from 3 to 15% (by weight) of transition element belonging to the group Ti, V, Cr, Mn, Co, Ni, Fe, Zr, Nb and Mo. However, these only retain a hardness lower than 190 Vickers units, for periods of maintenance of 1 week at temperatures lower than or equal to 400 ° C.
  • the invention relates to Al alloys whose heat stability is significantly higher.
  • the alloys according to the invention contain, in addition to the Al and the inevitable processing impurities, at least 5 to 20% (by weight) of Fe, and more than 0.05% Ni and 0.5% Mo.
  • the sum of the Ni + Mo contents must not exceed 8%, so as not to exceed the retention capacity of the alloying elements during rapid solidification (> 10 4 ° C / second) of the alloy.
  • the% Mo /% Ni ratio must be greater than 0.5 to obtain the desired hot stability. This stability is very much greater than that which a separate addition of Ni or Mo could confer; this point will be illustrated by examples.
  • One (or more) other refractory element (s) from the group Mn, Si, Cr, Ti, Hf, Zr, Nb, V, W can be added to this basic composition, for a lower overall content. at 5% by weight.
  • the alloys of preferred compositions comprise individually or in combination of 5 to 10% Fe, a ratio and / or a Mo content ⁇ 1%
  • These alloys obtained by rapid solidification (> 10 4 ° C / second), by any known means, present in the solid state of solidification either a single-phase structure (supersaturated solid solution based on Al) or a particular structure made up of this solid solution based on A1 and a fine precipitation of eutectoid type, of a phase (which we will call u) of filiform appearance whose width, on micrographic section, is of the order of 5 to 50 nm
  • This phase contains at least 1 Z by weight of Ni and 1% of Mo.
  • This microcrystalline ⁇ phase has the following interreticular distances: 0.38 - 0.203 to 0.211 - 0.147 - 0.125 - 0.107 nm its structure is probably cubic complex.
  • the size of the crystallites of this phase ⁇ is of the order of 1 nm, which results in the existence of several broad and diffuse rings on the electron diffraction radiographs.
  • the alloys were produced in the form of a ribbon 1 to 5 mm ⁇ 20 to 40 ⁇ m, by rapid solidification on a steel casting wheel, driven at a tangential speed of 45 m / second.
  • alloys 2, 7, 8 which are outside the scope of the invention have poor heat stability, relative to the other alloys according to the invention.
  • a minimum quantity of nickel (and of Mo) is essential to obtain the good properties of heat resistance: the preferred compositions (4, 5, 6 ) have optimal hot characteristics.
  • Table III gives the characteristics of hot resistance for longer-lasting holdings of the alloys (4 to 6) at 400 ° C.
  • the alloy 4 has a precipitation in semi-coherent platelets while in the alloy 8, the precipitation already consists of incoherent globules of Al FeNi type phase. .
  • the thermal stability of alloy 4 is associated with the slower decomposition kinetics observed on this alloy.
  • the alloys according to the invention can be used for parts of turbomachines operating at temperatures below 350 ° C for fairly long periods or operating at higher temperature for fairly short periods (missile bodies).
  • They can also be used in the form of coatings on substrates of different nature, and, optionally hardened by laser treatment or electronic bombardment.
