Definitions

  • the present invention relates to aluminum alloy parts having improved fatigue resistance and to a method for manufacturing said parts.
  • EP 144898 teaches an aluminum alloy containing by weight 10 to 36% of silicon, 1 to 12% of copper, 0.1 to 3% of magnesium and 2 to 10% of at least one element chosen from the group Fe, Ni, Co, Cr and Mn.
  • This alloy is applicable to the manufacture of parts intended for both the aeronautical and automotive industries, said parts being obtained by the technique of powder metallurgy comprising, in addition to shaping by compacting and spinning, an intermediate processing step thermal between 250 and 550 ° C.
  • this alloying element added to the others in an amount at least equal to 0.4% to have a suitable effect but not exceeding 1.5%, an amount beyond which the 'improvement obtained is no longer noticeable, had the consequence of increasing the fatigue resistance of the parts and this without harming neither the other properties obtained with the alloys of the prior art, nor their ability to be machined.
  • the invention also relates to a process for obtaining parts from such alloys.
  • the parts after being possibly subjected to machining, are heat treated between 480 and 530 ° C for 1 to 10 hours, then quenched in water before undergoing a tempering treatment between 150 and 200 ° C for 2 to 32 hours, which improves their mechanical characteristics.
  • Alloys no. 1, 2 and 3 were obtained by powder metallurgy, that is to say that they were melted at 900 ° C. and then atomized in a nitrogen atmosphere in the form of particles with a particle size of 300 ⁇ m. then compacted under 300 MPa in an isostatic press, spun in the form of a bar with a diameter of 40 mm.
  • the technique used was that of the "spray deposition" during which a deposit was obtained in the form of a cylindrical billet which was then transformed by spinning into a bar of diameter 40 mm. The bars originating from one or the other process were then treated for 2 hours between 490 and 520 ° C.
