Definitions

  • the present invention relates to a process for obtaining high strength Al-Zn-Mg-Cu type Al alloy spun products which in the treated state (type T6 or T7) have high ductility and toughness, in particular in the cross direction, as well as good resistance to corrosion under tension.
  • High strength spun products are already known which have high ductility and toughness characteristics in the long direction (see for example those described in French patent application 2 457 908).
  • alloys A and B Two alloys A and B were cast, the compositions of which are the following alloy A, outside the invention, constituting the control.
  • Alloy A semi-continuously cast in the form of 170 mm diameter billets, underwent a homogenization treatment for 24 hours at 460 ° C., was spun by reverse spinning at 400 ° C. ⁇ 10 ° C. in the form of cases of dimensions ⁇ 107 X 141 mm.
  • batch B3 whose homogenization conditions for dissolution, work hardening between quenching and tempering are located in the preferred field of the invention, appears to be particularly effective, in particular with regard to elongations at break in the cross direction of the bottom of the case which are more than four times higher than those of the control batch A.
  • batches B4x show that for a treatment of the T7 type with two bearings, it is possible to confer on the alloys in accordance with the invention a resistance to corrosion under particularly high stress.
  • alloy C outside the invention, constituting the control.
  • Each of the alloys was homogenized for 24 h at 475 ° C, peeled to a diameter of 170 mm and transformed by reverse hot spinning at the temperature of 350-400 ° C in the form of a bar with a diameter of 50 mm.
  • the bars were dissolved for 1 hour at 478 ° C, soaked in cold water and returned 24 hours at 120 ° C.
  • test specimen is shown in Figure 2.
  • a fatigue crack is initiated on the test specimen defined above, taken in the LR direction, from the body, under the conditions of standard ASTM E399 (0.45 ⁇ a / W ⁇ 0.55, propagation in fatigue d '' at least 1.3 mm, load less than 60% of the Pq).
  • the test piece cracked in fatigue, is then subjected to a slow bending test at three points.
  • the curve effort is recorded as a function of the speed of unwinding of the paper from the recorder (constant speed).
  • the K factor was calculated according to the formula given by standard ASTM E399 (Bend Specimen) which is: (in MPa ⁇ m)
  • the value of a used in the formula is the average value of the three measurements.
