Definitions

  • the invention relates to the use of an iron-nickel-cobalt alloy.
  • Iron-based alloys with about 36% nickel have been used for shaped shadow masks in monitors and televisions for a few years due to their small thermal expansion coefficients between 20 and 100 ° C.
  • Technical iron-nickel alloys with about 36% nickel in the temperature range of 20 to 100 ° C as prevail in conventional display tubes, in the annealed state, a thermal expansion coefficient between 1.2 and 1.8 x 10 -6 / K, as indicated in the Steel-Iron Material Sheet (SEW-385, Issue 1991).
  • Shaped shadow masks use advanced grades of about 36% nickel that achieve smaller thermal expansion coefficients in the temperature range of 20 to 100 ° C between 0.6 and 1.2 x 10 -6 / K.
  • an iron-nickel-cobalt alloy which has the following chemical composition (in% by mass):> 2.5-7% Co, 35.5-38% Ni + Co, ⁇ 0.1% Mn, 0.0005 - 0.004% B, balance Fe.
  • the contents of S are ⁇ 0.002% and C ⁇ 0.005%.
  • an iron-nickel alloy has been reported which has the following composition (in mass%): 27 to 47% Ni, ⁇ 22% Co, 0.005 - 0.1% Nb, ⁇ 0.01% C, 0.002-0 , 02% N, Fe remainder.
  • the following equation should be satisfied: 0.0000135 (% Nb) x (% N) 10.002.
  • Ni contents between 32 and 33% Co contents between 4.49 and 4.68%, Nb contents between 0.02 and 0.8%, Mn contents between 0.09 and 0.25% become thermal Expansion coefficient in the range of 0.51 to 0.56 x 10 -6 / C achieved.
  • the object of the subject invention is to provide an alternative use of a certain Fe-Ni-Co alloy, which has a low mean thermal expansion coefficient between 20 and 100 ° C but increased mechanical strength.
  • Nb at levels between 0.02 and 0.3% is particularly beneficial for improving hot and creep resistance at higher temperatures.
  • B at levels of up to 0.005% has an advantageous effect on improving the hot ductility of the alloy.
  • Preferred fields of application of the alloy are mirror mounts and frames in devices of lithography in chip production.
  • exemplary chemical compositions for the iron-nickel-cobalt alloys E1 thus produced are compared with another investigated iron-nickel-cobalt alloy (U1) and in comparison to exemplary prior art iron-nickel alloys with about 36% nickel (T1, T2, T3) with their mean thermal expansion coefficients between 20 and 100 ° C listed.
  • Table 1 Exemplary chemical compositions (in mass%) for the thus produced iron-nickel alloy E1 of the alloys U1 investigated and the alloys in the state of the art T1, T2, T3 with an indication of the mean thermal expansion coefficient between 20 ° C. and 100 ° C. ,
  • Further advantageous alloy variants contain, instead of or in combination of the stated Mo and C contents, an Nb content of between 0.02 and 0.3%. With the stated content of Nb, in addition to a further increase in mechanical strength at room temperature, improved hot and creep resistance is achieved at a higher temperature.
