Definitions

  • the present invention relates to a clock component comprising a high entropy alloy, and a method of manufacturing such a clock component.
  • the invention also relates to the use of a high entropy alloy for manufacturing a watch component.
  • the watch components, and particularly the barrel springs, are subject to strong constraints, in particular during their manufacturing processes, but also during their use.
  • the invention aims to overcome the drawbacks of the state of the art by providing a watch component having a higher mechanical strength and greater ductility.
  • a timepiece component comprising a high entropy alloy, the high entropy alloy comprising between 4 and 13 main elements forming a single solid solution, the high entropy alloy having a concentration in each main element between 1 and 55 atomic%.
  • a timepiece component comprising a high entropy alloy, the high entropy alloy comprising between 4 and 13 main elements forming a single solid solution, the high entropy alloy having a concentration in each main element between 1 and 55 atomic%.
  • the concentration in each main element is between 10 and 55 atomic%.
  • the high entropy alloy may comprise one or more interstitial elements among the following: C, N, B. These interstitial elements make it possible to further increase the mechanical strength of the alloy.
  • the high entropy alloy may comprise one or more elements of structural hardening among the following: Ti, Al, Be, Nb, preferably in a mass concentration of between 0.1 and 3%.
  • the watch component may be one of the following: a spring, a mainspring, a jumper spring, an anchor, a plate, an anchor, a rod, an anchor rod, an anchor fork , a wheel, an escape wheel, a shaft, a pinion, an oscillating weight, a winding stem, a crown, a watch case, a bracelet link, a watch bezel, a bracelet clasp.
  • a second aspect of the invention also relates to the use of a high entropy alloy for manufacturing a watch component, the high entropy alloy comprising between 4 and 13 main elements forming a single solid solution, the alloy having a concentration in each main element between 1 and 55 atomic%.
  • the figure 1 represents a barrel spring 1 according to one embodiment.
  • This barrel spring 1 is made of a high entropy alloy.
  • the entropy of mixing is high and makes the single phase thermodynamically more stable than the mixing of several phases.
  • the mainspring is preferably made of the high entropy alloy described in the publication " Metastable high-entropy dual-phase alloys overcome the strength-ductility trade-off, Zhiming Li et al, Nature 534, 227-230 (09 June 2016 ).
  • This high entropy alloy has the following formula: Fe 80-x Mn x Co 10 Cr 10 .
  • x is preferably between 25 and 79 atomic%.
  • the mainspring can be made of a Fe 35 Mn 45 Co 10 Cr 10 alloy.
  • the barrel spring thus produced has the advantage of combining a high limit at break and a high ductility.
  • the mainspring can be made of a Fe 40 Mn 40 Co 10 Cr 10 alloy.
  • the spring thus produced presents the advantage of having a high breaking strength and high ductility. It also operates according to a TWIN mechanism ("twinning induced plasticity").
  • the mainspring can be made of a Fe 45 Mn 35 Co 10 Cr 10 alloy.
  • the barrel spring thus produced has the advantage of still having greater breaking strength and greater ductility. It also works according to a TRIP mechanism ("transformation induced plasticity").
  • the mainspring can be made of a Fe 50 Mn 30 Co 10 Cr 10 alloy.
  • the barrel spring thus produced has the advantage of still having greater breaking strength and greater ductility. It operates according to a TRIP mechanism with the appearance of two phases, cfc and hc, by a clipping mechanism.
  • the invention is not limited to the manufacture of a mainspring. Indeed, other watch components could be made in the high entropy alloy Fe 80-x Mn x Co 10 Cr 10 , such as a spring, a rod, an ankle, a balance, an axis, a plate, an anchor, an anchor rod, an anchor fork, an escape wheel, a shaft, a pinion, an oscillating weight, a winding stem, a crown, a jumping spring, a watch case, a bracelet link, a watch bezel, a bracelet clasp ...
  • the figure 2 schematically represents the steps of a method of manufacturing the barrel spring of the figure 1 .
  • This method comprises a first step 101 for manufacturing a high entropy alloy ingot. To do this, the elements are mixed in pure form or pre-alloy, then they are fused and the whole is cast to form an ingot.
  • the method then comprises a step 102 of hot forging of the ingot.
  • the method then comprises a step 103 of hot rolling.
  • the process then comprises a cold rolling step 104.
  • the method then comprises a drawing step 105.
  • the process then comprises a cold rolling step 106.
