Definitions
- Iron-nickel-cobalt alloy process for producing and using the same
- the invention relates to an iron-nickel-cobalt alloy.
- Iron-based alloys with around 36% nickel have been used for shaped shadow masks in monitors and televisions for several years due to their small coefficients of thermal expansion between 20 and 100 ° C.
- Technical iron-nickel alloys with about 36% nickel have a thermal expansion coefficient between 1, 2 and 1, 8 x 10 "6 / K in the temperature range from 20 to 100 ° C, as they prevail in conventional display tubes, in the soft-annealed state, as described in the steel-iron material sheet (SEW-385, 1991 edition).
- the aim of the subject matter of the invention is therefore to provide a material for shadow masks which enables an even smaller average thermal expansion coefficient between 20 and 100 ° C than that iron-nickel alloys available today with approximately 36% nickel. Furthermore, a material variant with a relatively low thermal expansion but increased mechanical strength is to be produced.
- the first goal of a particularly low thermal expansion is achieved according to the invention by an iron-nickel-cobalt alloy for shadow masks for use in large flat monitors and screens, the chemical composition (in% by mass) being defined by 32.5
- the second goal is achieved by an iron-nickel-cobalt alloy for shadow masks for use in large flat monitors and screens, the chemical composition (in% by mass) being defined by 32.5
- the iron-nickel-cobalt alloy described is melted in an arc furnace or vacuum induction furnace and cast in the form of blocks.
- a process e.g. VAR
- VAR vacuum induction furnace
- Preferred fields of application of this alloy are frames of shadow masks for use in display tubes as well as mirror mounts and frames in lithography devices for chip production.
- Table 1 shows exemplary chemical compositions for iron-nickel-cobalt alloys (E1, E2, E3, E4) according to the invention in comparison to another iron-nickel-cobalt alloy (U1) investigated and in comparison to exemplary ones from the prior art iron-nickel alloys with about 36% nickel (T1, T2, T3) with their average thermal expansion coefficients between 20 and 100 ° C.
- Table 1 Exemplary chemical compositions (in mass%) for the iron-nickel alloys E1, E2, E3, E4 according to the invention, the alloys U1 investigated and the alloys in the prior art T1, T2, T3 with indication of the average coefficient of thermal expansion between 20 ° C and 100 ° C.
- the material variants E5 and E6 of the alloy according to the invention achieve a yield strength Rp0.2 which is about 10 to 20% higher than that of the prior art alloy T2.
- An increase in mechanical strength was achieved by alloying 0.30% Mo and 0.047% C (E5) and 0.036% C (E6).
- the alloy E5 according to the invention also achieves a low coefficient of expansion of 0.45 x 10 " ⁇ / K between 20 and 100 ° C, so that with the alloy E5 a combination of increased strength and low thermal expansion was achieved In these alloys according to the invention, very low Mn and Si contents are decisive for achieving the technological properties.
- Further advantageous alloy variants according to the invention contain an Nb content instead of or in combination of the Mo and C contents mentioned between 0.02 and 0.3%. With the stated Nb content, in addition to a further increase in mechanical strength at room temperature, improved thermal and creep resistance at higher temperatures is also achieved.
- Table 2 Exemplary chemical compositions (in% by mass) for the iron-nickel alloys E5 and E5 according to the invention compared to the alloy according to the prior art T2 with indication of the average coefficient of thermal expansion between 20 ° C. and 100 ° C. and the mechanical yield point Rp0, 2 after a heat treatment of 14 minutes at 790 ° C.
