Definitions

  • plastic deformation of an amorphous metal alloy is only possible by the creation of sliding strips. This deformation mechanism is totally different from that of crystalline metal alloys. Plastic deformation of an amorphous metal alloy is generally undesirable because it results in a rapid breakage of the stressed part.
  • Figure 1 is a ductility / brittleness diagram depending on the annealing conditions
  • metal alloy capable of forming, by cooling an amorphous or essentially amorphous metal alloy, called "metallic glass", in because of the excellent mechanical properties resulting from their particular structure.
  • the parameters of the projection and the cooling are chosen so as to obtain a cooling rate of the liquid metal alloy greater than 10000 ° C./s.
  • a cooling rate obtained by hyper-quenching, indeed favors the ductility by the formation of "free volume" in the structure of the metallic glass.
  • Tg and Tx are little influenced by the conditions of elaboration of the ribbons.
  • Form fixing relaxation annealing was performed on 30mm long tapes wound inside aluminum rings with an internal diameter of 7.8mm, which is close to typical spring bending diameters. barrel.
  • a logotherm® resistance furnace in ambient atmosphere was used.
  • the rings are placed on thermostatic alumina studs in the center of the oven to ensure temperature homogeneity and rapid heat transfer.
  • the treatment time is counted from the moment of closure of the oven door. One second before the end of the countdown, we take the ring with a pair of pliers and soak it very quickly in about 2 liters of water at room temperature.
  • the sample is considered fragile if the deformation at rup ⁇ ture is less than 2% (without any prior plastic deformation).
  • These curves resulting from tests at 520 ° and 570 ° C show that the fixing behavior is similar to that of the alloy Ni 53 Nb 2 oZr 8 TiCo 6 Cu 3 and that at 520 ° C, embrittlement does not occur. reached for the durations tested (up to 30 minutes).
  • a metal glass ribbon was placed in the slit of the installation by making it undergo an elastic deformation and the fixing process was carried out in an oven under ambient atmosphere between two ceramic studs thermostated at 430 ° C., for 3 min, followed by the tempering of the pose.
  • the ribbon once out of his pose, shows a free form corresponding almost perfectly to the desired free form.
  • Figures 5a, 5b respectively represent the desired free shape and the free form with the curvatures contracted at 60% of the setting.
  • the copper installation is placed perpendicular to the hot gas distribution tube. It could also be maintained with a certain inclination, for example 45 °.
  • the fixture is mounted on a three-position linear guiding system for i) placing the copper fixture in a raised position, out of range of the gas jet ii) positioning it in the hot gas jet and iii) immersing it immediately in a cooling liquid, such as water for example, at the end of hot treatment.
  • the setting containing the tape is placed in a vacuum oven, or between two ceramic hot plates, these modes being given by way of non-limiting examples.
  • the shaping can also be carried out in two or more stages of heat treatment.
  • this step can not be transposed directly to the metal glass ribbons: as indicated above, the plastic deformation of the metal glasses is strongly discouraged.
  • FIG. 6a shows the armoring and disarming characteristic of a spring of alloy Ni 53 Nb 2 oZr 8 TiCo 6 Cu 3 of 81 ⁇ of thickness shaped by cold plastic deformation for the internal end (shell), then by heating hot gas jet in a setting as described above, with conditions corresponding to a fixing coefficient of 60%.
  • the spring gives a completely satisfactory behavior, making it possible to reach the desired torque and number of turns, and shows a good fatigue behavior.
  • the spring measured in FIG. 6a comprises a shell formed by cold plastic deformation over a greater or lesser length (typically 40 mm in the case of FIG. 6a) with good reproducibility, and the resulting mainspring spring shows good performance.
  • the inventors therefore wanted to know if the method for obtaining the curvature of the shell by plastic deformation was applicable to the entire spring.
  • the shaping by cold plastic deformation takes place in two stages: first, the outer end of the ribbon is introduced in order to apply a negative curvature according to the desired theoretical curvature up to the point of inflection. Then the inner end is introduced to apply a positive curvature according to the theoretical curvature.
  • FIG. 6b shows the armoring and disarming characteristic of a Ni 53 Nb 2 oZr 8 Tii 0 Co 6 Cu 3 alloy spring of 81 ⁇ thickness shaped by cold plastic deformation only. Despite the absence of fixing by heat treatment, the behavior of the spring is in all respects comparable to that of Figure 6a.
  • the shaping of metal glass alloy ribbons by plastic deformation is not limited to the alloy only Ni 53 Nb 2 oZr 8 iioCo 6 Cu 3 .
  • the alloys of Figures 3 and 4 can also be shaped by plastic deformation.
  • Other amorphous Ni base alloys, Fe and / or Co may also be shaped with at least one plastic deformation step, and may be heat-treated to obtain additional curvature.
