Definitions
- the invention relates to the use of a low-expansion iron-nickel alloy with at least 34% nickel.
- the mean coefficients of expansion are between 1.78 x 10 -6 / ° C and 4.19 x 10 -6 / ° C and are therefore relatively high for the intended use. This is in view of the fact that if the elements V, Cr, Mo, W are specified in cooperation with a closely selected Ni range ( ⁇ 36.5%), no further reduction in the coefficient of thermal expansion is possible.
- Fe / Ni ratios would be between 1.70 and result in 1.86.
- the lower Ni content including the elements mentioned would the remainder is Fe 63.84%, which means an Fe / Ni ratio of 1.824.
- the the upper Ni content including the elements mentioned is the remainder Fe 61.84, from which an Fe / Ni ratio of 1.67 is calculated.
- the Spreading range of this alloy also known as Invar alloy (1.67 - 1.86) to be considered large.
- DE-A 36 42 205 discloses an Fe-Ni alloy that can be used for shadow masks.
- a reference alloy is used for the alloy claimed in this document, which may contain further constituents of at least one of the elements Ti, Zr, B, Mo, Nb, N, P, Cu, V, Mg, Co, W.
- the comparison alloy contains 0.36% Mn and 0.01% C, whereby the coefficient of thermal expansion is given as 1.4 x 10 -6 / K.
- the object of the invention is now to provide a low-expansion iron-nickel alloy with the aim of minimizing thermal Expansion coefficients in the temperature range from 20 to 100 ° C for TV tubes as well as good hot and cold formability, in particular in the processing of the alloy for components of color television sets.
- This object is achieved by using the single claim low-expansion iron-nickel alloy.
- the invention derives its advantageous effect from the stated iron-nickel ratio. This effect on the expansion coefficient is supplemented by the targeted adjustment of the above-mentioned others Alloy components and the manufacturing-related admixtures.
- the Alloy according to the invention is also characterized by a excellent workability and demands in the production of Shadow masks no additional procedural steps. It continues to show one long-term stability of their thermal according to the needs Characteristics.
- iron-nickel alloys with a total content of aluminum and Silicon from 0.075 to 0.45% preferred. With such alloys desired low coefficient of thermal expansion in the above Set temperature ranges reliably. With a maximum manganese content In addition to a maximum of 0.3% Si, the aluminum content in the range of max. 0.01%.
- E1 E2 E3 ST1 ST2 Cr 0.01 0.01 0.02 0.06 0.05 Ni 35.75 36,10 35,20 36.35 36.40 Mn 0.02 0.03 0.02 0.25 0.27 Si 0.02 0.04 0.03 0.19 0.18 Mo 0.04 0.02 0.03 0.04 0.03 Ti 0.01 0.01 0.01 0.01 0.01 Nb 00:01 ⁇ 0.01 ⁇ 0.01 ⁇ 0.01 ⁇ 0.01 Cu 0.03 0.02 0.03 0.05 0.03 Fe 63.80 63,40 64,30 62,90 62,95 S ⁇ 0.002 ⁇ 0.002 ⁇ 0.002 ⁇ 0.002 ⁇ 0.002 P 0,002 0,002 0,002 0,006 al 0.230 0.37 0.38 0.005 0,003 mg 0,002 0,002 0,003 0,003
- the coefficient of thermal expansion of the alloys E1 according to the invention for the temperature range from 20 to 100 ° C after 30 minutes of annealing 950 ° C determined. It is therefore around 30% lower than that at the level of Alloy examples ST1 and ST2 belonging to the technology. Since the material according to the invention also with maximum oxide lines of 2.2 according to DIN 50602 is metallurgically clean and is extremely hot and cold formable, it is ideal for manufacturing e.g. of shadow masks and Color picture tubes.
