Definitions

  • the invention relates to a low-thermal expansion iron-nickel alloy with special mechanical properties.
  • iron-base alloys with about 36% nickel have low expansion coefficients in the temperature range between 20 and 100 ° C. Therefore, these alloys have been used for some decades, where even with temperature changes constant lengths are required, such as precision instruments, watches, bimetals or shadow masks for color TV sets and computer monitors.
  • the Invar alloy has the following composition (in mass%) 33 to 38% nickel, 0.5 to 1.0% cobalt, 0.01 to 1.3% niobium, 0.5 to 4% molybdenum, 0.2 up to 1.5% chromium, 0.05 to 0.35% carbon, 0.1 to 1.2% silicon, 0.1 to 0.9% manganese, max. 0.1% magnesium, max. 0.1% titanium, remainder iron, where the sum of Mo + Cr is between 1.2 and 5.0% and the sum of niobium and carbon is between 0.1 and 0.6%.
  • the KR 1020000042608 discloses a high strength Invar alloy wire and a method of making the same.
  • the alloy used contains (in% by mass) not more than 0.1% nitrogen, 0.01 to 0.2% niobium, 0.3 to 0.4% carbon, 33 to 38% nickel, 0.5 to 4% molybdenum, 0.2 to 1.5% chromium, 0.1 to 1.2% silicon, 0.1 to 0.9% manganese, 1.0 to 10% cobalt and, if necessary, additions of Al, Mg and Ti in each case to 0.1%, balance iron.
  • the aim of the subject invention is to provide a low thermal expansion creep-resistant iron-nickel alloy with special mechanical To provide properties.
  • a manufacturing method for wire-shaped components made of this alloy will be presented.
  • the material should be usable for certain applications, the alloy should have a low coefficient of thermal expansion.
  • an iron-nickel alloy of the following composition: C 0.05 to 0.5% Cr 0.2 to 2.0% Ni 33 to 42% Mn ⁇ 0.1% Si ⁇ 0.1% Not a word 1.5 to 4.0% Nb 0.01 to 0.5% al 0.1 to 0.8% mg 0.001 to 0.01% V Max. 0.1% W 0.1 to 1.5% Co Max. 2.0% optional Zr > 0 to ⁇ 0.2% and / or optional B > 0 - 0.01%, wherein, if necessary, the element Mo can be proportionally substituted by the element W.
  • a preferred variant of the iron-nickel alloy according to the invention is reproduced (in% by mass) as follows: C 0.1 to 0.4% Cr 0.5 to 1.5% Ni 34 to 40% Mn ⁇ 0.08% Si ⁇ 0.08% Not a word > 2.0 to ⁇ 3.5% Nb 0.05 to 0.4% al 0.2 to 0.5% mg 0.001 to ⁇ 0.01% V Max. 0.1% W 0.2 to ⁇ 1.0% Co 0 to 1.0% Fe Remainder and production-related admixtures.
  • Another variant is formed by (in% by mass): C > 0.15 to ⁇ 0.4% Cr 0.6 to max. 1.2% Ni 35 to 40% Mn ⁇ 0.08% Si ⁇ 0.08% Not a word > 2.0 to ⁇ 3.0% Nb 0.05 to ⁇ 0.3% al > 0.1 to ⁇ 0.5% mg > 0 to ⁇ 0.01% V Max. 0.1% W 0.25 to 1.0% Co 0 to max. 0.5% B > 0 to ⁇ 0.01% Fe Remainder and production-related admixtures.
  • the inventive composition of the alloy is distinguished from the prior art in that the Si and Mn contents are kept as low as technically possible. It is known that in terms of the coefficient of thermal expansion, a strong dependence of the elements silicon and manganese is given. On the other hand, these elements are metallurgically necessary to ensure sufficient processability. This applies in particular to the hot forming of billets and wire rod.
  • the chemical composition according to the invention therefore makes it possible to dispense with the elements silicon and manganese as far as possible, whereby the negative influence of these elements on the thermal expansion coefficients can be avoided and, at the same time, a good processability of the alloy is achieved. For this reason, the sum of Mn + Si should not exceed (in% by mass) 0.2%. If technically feasible, the sum of Mn + Si should be ⁇ 0.1%.
  • the alloy according to the invention has a nickel content of between 35 and 38%, a chromium content of> 0.6 to ⁇ 1.2%, a molybdenum content of between 2.1 and 2.8%, and an aluminum content of between 0.2 and 0 , 4% and a tungsten content> 0.25 to ⁇ 1.0%.
  • the ratio W: Cr: Mo should, according to another idea of the invention, be approximately 1: 2: 5. However, the proportion of said elements in the alloy according to the invention must be specified so that the desired thermal expansion coefficient is not exceeded.
  • the alloy according to the invention has a thermal expansion coefficient ⁇ 4 ⁇ 10 -6 / K, in particular ⁇ 3.5 ⁇ 10 -6 / K.
  • the alloy according to the invention can be used as a wire for transmission lines, in particular as a core wire for transmission lines.
  • the alloy according to the invention can be present for the preferred applications in the form of sheet metal, rod, strip or wire material.
