Definitions
- the present invention relates to an iron / nickel alloy with low coefficient of expansion.
- Iron / Nickel alloys with low coefficient of expansion containing by weight between 35% and 40% of Nickel are well known.
- Nickel and Iron alloys In addition to Nickel and Iron, these alloys always contain impurities such as Sulfur, Phosphorus, Oxygen, Nitrogen and Carbon resulting from processing. They may also contain elements such as Cobalt, Chromium, Copper, Molybdenum, Vanadium, Niobium and Silicon added in particular to adjust their mechanical properties. But, due to the presence of impurities, these alloys are difficult to deform hot by rolling or forging.
- the aim of the present invention is to propose an alloy Low Manganese Iron / Nickel with Good Hot Ductility and can be produced by conventional methods.
- the invention relates to an Iron / Nickel alloy as defined in claim 1.
- the chemical composition is such that: O ⁇ 0.005% N ⁇ 0.003% S ⁇ 0.0005%
- the nickel content must be between 35.8% and 36.3% and better still between 35.9% and 36.2% and, Cr ⁇ 0.1%, Cu ⁇ 0.1%, Mo ⁇ 0.1%, V ⁇ 0.1%, Nb ⁇ 0.1%
- the invention also relates to a strip of iron / nickel alloy according to the invention, obtained by hot and then cold rolling, of width greater than 400 mm and whose coefficient of linear expansion between 20 ° C and 100 ° C is less than 0.9x10 -6 / o K.
- the alloy according to the invention is an alloy based on Iron and Nickel containing, from 35.5% to 37% of Nickel, possibly elements of complementary alloys such as Cobalt, Chromium, Copper, Molybdenum, Vanadium or Niobium in contents of less than 3%, intended to adjust the mechanical characteristics according to uses.
- the alloy imperatively contains less than 0.1% and preferably less than 0.05% Manganese because this element increases the coefficient of thermal expansion.
- Calcium and Magnesium contents are limited to 0.002% to avoid the formation of large inclusions which may cause pitting during chemical cutting, this is particularly the case when the alloy is used in the form of thin strips for the manufacture of shadow masks for cathode ray tubes.
- the alloy contains less than 0.005% aluminum and less than 0.005% and preferably less than 0.003% nitrogen. He must also contain less than 0.01% and preferably less than 0.005% of Oxygen.
- the nickel content should preferably be between 35.8% and 36.3%, and better still between 35.9% and 36.2%; the optimal content being 36.05%.
- Cobalt is an element that can be partially substituted Nickel up to 10%, but this element has disadvantages when the alloy has to undergo a chemical attack for example to make chemical etching, too, its content should preferably be limited to 0.5%, in particular when the alloy is intended to manufacture shadow masks for cathode ray tubes.
- the alloy When the alloy is used to manufacture thin strips intended for stamping, it must contain less than 0.005 % of Carbon in order to have the lowest possible elasticity limit which is favorable for a good drawing ability. .
- the hydrogen content must be less than 0.001% and preferably less than 0.0005% to avoid the formation of blisters.
- the boron content must remain below 0.0004 % in order to avoid the formation of boron nitrides on the surface of the products during heat treatments. These nitrides form a powdery layer which causes poor adhesion of the darkening layer produced on the shadow masks.
- the rest of the chemical composition of the alloy consists with Iron.
- This alloy makes it possible to manufacture by hot rolling ingots or slabs, then by cold rolling, thin strips, less than 0.3 mm thick and more than 400 mm wide, used in particular for the manufacture of shadow masks for screens cathodic.
- the hot rolling was carried out without cracking.
- the coefficient of expansion was 0.81x10 -6 / o K.
- the elastic limit E0.2 was 270MPa
- the coercive field was 0.45 Oe.
- the tape had very good chemical etching ability. All of these properties made it particularly suitable for the manufacture of shadow masks for cathode ray tubes.
- the alloy according to the invention can also be used especially in metrology or for the manufacture of bimetallic strips.
