Definitions

  • the invention relates to an Al alloy which can be used for the manufacture of hollow bodies under pressure, and in particular, metal bottles for compressed gases.
  • the alloys according to the invention therefore have the following weight composition (in%): Rest: AI
  • the Mg content is preferably kept below 2%, and even 1.95%, and the Zr content is preferably between 0.10 and 0.18%, the Fe + Si contents being ⁇ 0, 25% with Fe Z 0.12%, an Mn Z content 0.10% and / or the Zn content - 6.75.
  • the structure is recrystallized, but with large grains.
  • the manufacturing and control process are similar to those described in EP-A-0257167, but preferably the treatment of final income type T73 is replaced by an income in 3 stages, the 1st stage being carried out between 105 and 120 °. C for 6 to 12 h, the 2nd step being carried out between 170 and 190 ° C for 0.5 to 20 h and the 3rd step being carried out between 105 and 120 ° C, for 12 to 36 h.
  • durations and temperatures actually used are chosen by a person skilled in the art so as to obtain both a high electrical conductivity (corresponding to good resistance to corrosion under tension) and a high elastic limit.
  • Example 1 Replacement of Cr by Zr for two-phase income type T73.
  • the burst characteristics are correct (longitudinal crack for the most part, unbranched, limited to a sector of angle ⁇ 90 ° around the main crack, limited towards the bottom and towards the neck at areas whose thickness is less than 1.5 times the thickness of the body), the developed length of the crack was noted as a good indication of the ability to burst: the longer the crack, the more approximates the conditions for which the burst would be bad.
  • the mechanical resistance and the resistance to corrosion under stress are linked in a one-to-one way, which makes it better to speak of a loss on the compromise mechanical resistance / resistance to corrosion under stress.
  • the replacement of chromium by zirconium negatively affects the corrosion resistance or the mechanical resistance, depending on the duration of the maintenance at the second level which one chooses.
  • the following example shows the gain that can be obtained by performing an income in three stages on the bottles manufactured in alloy 2 according to the range of the previous example.
  • Electrical conductivity is taken as an indicator of resistance to stress corrosion, in accordance with standard practice. All values in the table below are averages of 3 individual values.
