Definitions

  • Ferromagnetic alloys based on iron, nickel or cobalt currently used for the production of spirals have an abnormally positive CTE in a range of about 30 ° C around the ambient temperature, due to the proximity of their Curie temperature. In the vicinity of this temperature, the magnetostrictive effects which decrease the Young's modulus of these alloys disappear, leading to an increase in the modulus. In addition to the fact that this temperature range is relatively narrow, these alloys are sensitive to the effects of magnetic fields. These modify the elastic properties of the spirals irreversibly and thus change the natural frequency of the mechanical oscillator. In addition, the elastic properties of the ferromagnetic alloys vary with the rate of cold work hardening, which requires to control exactly this parameter during the manufacture of the spiral.
  • the CTE values sought for the spirals made with this family of alloys are adjusted by a thermal precipitation treatment which also fixes the final shape of the spiral by relaxation.
  • Hf is in solid solution in Nb over a very wide concentration range (up to 30% at.).
  • the spiral alloy Nb-Hf may further contain one or more additional elements such as Ti, Ta, Zr, V, Mo, W, Cr in concentrations such that no precipitation occurs during the form fixing operation of the spiral.
