Definitions

  • the present invention relates to an iron-nickel alloy.
  • Iron-nickel alloys whose chemical composition includes, by weight, from 27% to 60% nickel, from 0% to 7% cobalt, the rest being iron and impurities resulting from processing, are used in the form of laminated strips cold and annealed, in particular for manufacturing soft magnetic cores.
  • the annealing carried out on very cold-worked cold rolled strips, has the advantage of giving these alloys a cubic recrystallization texture whose magnetic properties are very favorable for certain applications such as wound cores for magnetic amplifiers.
  • the iron-nickel alloy strips with cubic texture have a very hysteresis cycle rectangular (Br / Bs> 95%).
  • These alloys have the disadvantage of being difficult to manufacture.
  • the annealing temperature range favorable for obtaining good texture and satisfactory magnetic properties is too narrow, below 25 ° C, so that the manufacturing is reliable, in particular because the position of this temperature range depends on poorly known parameters.
  • the object of the present invention is to remedy this drawback by offering an iron-nickel alloy easier to manufacture than the alloy according to the art prior.
  • the subject of the invention is an iron-nickel alloy, the chemical composition of which comprises, by weight: 30% ⁇ Ni + Co ⁇ 85% 0% ⁇ Co + Cu + Mn ⁇ 10% 0% ⁇ Mo + W + Cr ⁇ 4% 0% ⁇ V + If ⁇ 2% 0% ⁇ Nb + Ta ⁇ 1% 0.003% ⁇ C ⁇ 0.05% 0.003% ⁇ Ti ⁇ 0.15% 0.003% ⁇ Ti + Zr + Hf ⁇ 0.15% 0.001% ⁇ S + Se + Te ⁇ 0.015% the remainder being iron and impurities resulting from the preparation, the chemical composition satisfying, moreover, the relation: 0% ⁇ Nb + Ta + Ti + Al ⁇ 1%
  • the chemical composition is such that: 0.005% ⁇ Ti ⁇ 0.05% and 0.001% ⁇ Hf + Zr ⁇ 0.025%
  • the manganese content must be greater than 0.05% and it it is not useful if it is greater than 1%. Similarly, it is preferable that Nb + Ta ⁇ 0.05%.
  • the invention also relates to a cold-rolled strip of iron-nickel alloy according to the invention whose recrystallization texture is cubic of the type (100) ⁇ 001>, and its use for the manufacture of a tube shadow mask cathode visualization or toric magnetic core.
  • the inventors have unexpectedly found that by adding to a iron-nickel alloy furthermore in accordance with the prior art, a small amount of titanium, possibly accompanied by small amounts of Zr or Hf, in the presence small amounts of S, Se or Te, and possibly Nb, Ta or Mn, we significantly increased the annealing temperature range of the alloy allowing to obtain a cubic texture (100) ⁇ 001> very favorable for obtaining good magnetic properties.
  • the width of the domain of satisfactory temperature exceeds 50 ° C whereas usually this width is below 25 ° C.
  • the affected iron-nickel alloys likely to have a structure cubic contains mainly iron and nickel, nickel can be partially substituted by cobalt. They may also contain, in particular, copper, manganese, molybdenum, tungsten, vanadium, chromium and silicon.
  • the rest of the composition consists of iron, the elements specific to the invention, and impurities.
  • This alloy can be produced in an arc furnace, continuously cast in the form slab or thin strip, or ingot, then hot rolled in the form of hot strip.
  • the hot strip is then cold rolled with a rate work hardening greater than 80%, and preferably greater than or equal to 90%, for get a cold rolled strip.
  • Heat treatment can also be carried out directly on the cold rolled strip, possibly with less stress on the research of magnetic properties. This is particularly the case when the content in nickel is close to 36% and that the strip is used for the manufacture of shadow masks for cathode ray viewing tubes; the cubic texture is, indeed, particularly favorable to a good quality of the drilling of holes by chemical etching.
  • Annealing is then carried out at a temperature above 550 ° C and below the secondary recrystallization temperature. When he it is not essential to have a particularly low coercive field, the annealing temperature is generally less than 800 ° C.
  • the chemical compositions of the alloys were, by weight%: Fe Or Mn Yes VS S Al Ti Hf AT ball 36.1 0.4 0.09 0.005 7 ppm ⁇ 0.005 0 0 B ball 36.4 0.3 0.1 0.012 30ppm 0.01 0.019 0.007
  • the critical temperatures were: 83% 90% 95% AT 970 ° C 1020 ° C 1040 ° C B 1060 ° C 1090 ° C 1090 ° C
  • the alloys were manufactured 1, 2 and 3 according to the prior art and the alloys 4, 5 and 6 according to the invention. These alloys were cold rolled in the form of strips of 0.05 mm thickness with 95% work hardening rates, then we determined the range of annealing temperature to obtain a cubic structure (100) ⁇ 001> as well as the magnetic properties mentioned above.
