Definitions

  • the invention relates to a low-expansion iron-nickel alloy.
  • iron-based alloys with 36% nickel have a low coefficient of expansion in the temperature range of 20 and 100 ° C. For this reason, these alloys have been used for several decades where constant lengths are required even when the temperature changes, such as precision instruments, watches, bimetals. With the development of color television sets and computer monitors in the direction of higher resolution, color fidelity and contrast strength even under unfavorable lighting conditions, and in particular with regard to the development of ever flatter and larger screens, iron-nickel materials are increasingly being used for shadow masks.
  • an iron-based alloy with at least 34% nickel with a lower coefficient of thermal expansion in the temperature range from 20 to 100 ° C of below 1.0 x 10 "6 / K could be developed by the Manganese content was kept below 0.1% and the iron / nickel ratio Fe / Ni was chosen between 1.75 and 1.83.
  • Typical values of the coefficient of thermal expansion in the temperature range from 20 to 100 ° C. are approximately between 0.6 and 0 , 9 x 10 "6 / K.
  • DE-A 22 17 280 relates to a pinhole in color picture tubes, the material of which is an iron-nickel alloy with a specific thermal expansion in the temperature range of 20-80 ° of 0-2, preferably from 0.6 to 1.2 x 10 " 6 / C of the following composition (in% by weight) is: 30 - 45% Ni, 0 - 2.5% Mn, 0 - 2% Si, 0 - 2% C, 0 - 8% Co, 0 - 11% Cr, 0 - 3% W, balance iron preferred alloy should have the following composition (in% by weight): 30-31% Ni, 4-8, preferably 5-7% Co, balance iron.
  • An iron-nickel alloy is known from JP-A 6-336655, which has a Ni content of between 35 and 36% by weight of Co contents of between 0 and 0.7% by weight.
  • iron-based alloys with approximately 32% nickel and 5% cobalt have an even lower coefficient of thermal expansion in the temperature range from 20 to 100 ° C. Therefore, these alloys are used for the highest requirements regarding thermal length stability. However, due to the high alloy costs due to the high cobalt content, these alloys are not widely used in industry.
  • an alloy which achieves a coefficient of thermal expansion in the temperature range from 20 to 100 ° C. even below 1.0 x 10'6 / K.
  • the alloy costs must be significantly lower than that of the iron-based alloy with about 32% nickel and 5% cobalt.
  • the object of the invention is to provide a low-expansion iron-nickel alloy which, when using inexpensive alloy elements, nevertheless achieves optimal thermal expansion coefficients in the temperature range from 20-100 ° C. and which should be usable for different applications.
  • the alloy particularly when processing the alloy into shadow masks for color television sets, must have good hot and cold formability.
  • the alloy according to the invention contains max. 0.009% carbon, max. 0.1% manganese, max. 0.1% silicon and max. 0.1% aluminum and the usual manufacturing-related additions in only a very small amount with residual iron.
  • the alloy according to the invention is characterized by excellent processability and requires no additional process steps in the production of shadow masks. It also shows the long-term stability of its thermal properties that meets the needs.
  • the alloy according to the invention achieves very low coefficients of thermal expansion in the temperature range from 20 to 100 ° C. from below 0.6 x 10 " ⁇ / K.
  • a higher manganese content of at least 0.2% is essential for good hot formability.
  • the alloy according to the invention is both very good hot and cold formable even at very low manganese contents of less than 0.05%.
  • This goal is also achieved by using a low-expansion iron-nickel alloy that (in mass%) for setting a thermal expansion coefficient ⁇ 0.6 x 10 "6 / K in the temperature range from 20 to 100 ° C in addition to a maximum of 0.009 % C, max.0.1% Mn, max.0.1% Si and max.0.1% AI, 0.5 to 2.0% Co and 35.0 to 36.0% Ni, balance iron and contains manufacturing-related admixtures, both for
  • AK AK (20-100 ° C): Average coefficient of thermal expansion for the temperature range 20 to 100 ° C.
  • the average thermal expansion coefficient in the temperature range from 20 to 100 ° C. of the alloy E according to the invention is, at 0.44 ⁇ 10 6 / K, significantly lower than the coefficients of the alloy examples ST1, ST2, ST3 and ST4 belonging to the prior art.
  • the specified alloying elements chromium, titanium, copper, sulfur, phosphorus, magnesium, zirconium and boron are considered to be additives due to the manufacturing process.
