Abstract
The invention relates to a low-expansion iron-nickel alloy, which to adjust a coefficient of thermal expansion of < 0.6 x 10<-6>/K at between 20 and 100 DEG C contains (in % by mass) in addition to up to 0.009 % C, up to 0.1 % Mn, up to 0.1 % Si and up to 0.1 % Al, between 0.5 and 2.0 % Co and between 35 and 36 % Ni, the remainder being made up of iron and production-related impurities.
Description
The present invention relates to a kind of iron-nickel alloy of low bulk.
As everyone knows, the ferrous alloy with 36% nickel has the low coefficient of expansion when temperature is 20-100 ℃.So these alloys are being used in the occasion that also requires to keep constant length when those temperature change in nearly recent decades always, precision instrument for example, clock and watch, bimetal.Along with colour television set and computer monitor to high definition, the true to nature and high contrast strength development of high color, even under disadvantageous light condition situation, particularly for display screen under the situation that more and more complanation and increasing direction develop, increasing iron nickel material is used to shadow mask.Technology iron-nickel alloy with about 36% nickel is 20-100 ℃ of temperature range, and as residing scope in conventional picture tube, its thermal expansivity is approximately 1.2 * 10 under the softening annealing state
-6/ K or even also want big, indicate in ferrous materials handbook (SEW-385,1991 editions) as it.
For satisfying the requirement that improves day by day, developed a kind of ferrous alloy that contains at least 34% nickel according to DE-A 4402684, this kind alloy has 1.0 * 10 20-100 ℃ of temperature range
-6The lower thermal expansivity that/K is following is by manganese content is kept below 0.1%, and the Fe/Ni ratio is chosen between the 1.75-1.83.Be approximately 0.6-0.9 * 10 at its typical thermal expansivity of 20-100 ℃ of temperature range
-6/ K.
DE-A 2217280 relates to a kind of eyelet aperture of colour picture tube, and its material is for to be expanded to 0-2 * 10 at 20-80 ℃ of temperature range specific heat
-6/ K is preferably 0.6-1.2 * 10
-6The iron-nickel alloy of/K, it has following composition (weight %): 30-45% nickel, 0-2.5% manganese, 0-2% silicon, 0-2% carbon, the 0-8% cobalt, 0-11% chromium, 0-3% tungsten, surplus is an iron.Preferred alloy should have following composition (weight %): 30-31% nickel, and 4-8%, preferred 5-7% cobalt, surplus is an iron.
Can know a kind of nickeliferous 36% cold tough Rhometal from 1973 international nickel DE-business documentation (DE-Firmenschrift derInternational Nickel) the 18th page, this alloy is to be prepared by less all the other constituent contents (weight %): 0.1% carbon, 0.3% silicon, 0.3% manganese, 0.015% sulphur, 0.015% phosphorus, 0.05% aluminium, 0.02% bronze medal, 0.1% cobalt, 0.1% chromium and 0.03% magnesium.
Announced a kind of iron-nickel alloy from commercial specification sheets (the DE-Firmenprospekt derInternational Nickel) the 12nd page of international nickel DE-in 1973.The nickel of this alloy 5-6 weight % replaces at room temperature making the bigger reduction of thermal expansivity in the iron-nickel alloy that contains 36 weight % usually with cobalt, but wherein available low-expansion coefficient scope narrows down.
Can know a kind of iron-nickel alloy from JP-A 6-336655, this alloy cobalt contents when nickel content 35-36 weight % is 0-0.7 weight %.
People also further know, the ferrous alloy that contains about 32% nickel and 5% cobalt 20-100 ℃ of temperature range have also will be lower thermal expansivity.So these alloys are applied to having in the purposes of peak demand for hot length stability aspect.But owing to high cobalt contents has improved cost of alloy, so these alloys are not widely used in technical field.
The shadow mask that is used in large-scale pure flat display screen requires a kind ofly also to be lower than 1.0 * 10 at 20-100 ℃ of its thermal expansivity of temperature range
-6The alloy of/K.Be lower than the ferrous alloy that contains about 32% nickel and 5% cobalt but its cost of alloy must be bigger.
Purpose of the present invention just provides a kind of iron-nickel alloy of low bulk, and this alloy can obtain best thermal expansivity 20-100 ℃ of temperature range by adding more cheap alloying element, and can be applied in the different Application Areass.
This alloy must have good hot and cold deformation performance especially when being processed into the colour television set shadow mask simultaneously.
This purpose can reach by a kind of iron-nickel alloy of low bulk, for this alloy is adjusted to less than 0.6 * 10 at the thermal expansivity of 20-100 ℃ of temperature range
-6/ K, this alloy be except the carbon of (quality %) maximum 0.009%, and maximum 0.1% manganese outside maximum 0.1% silicon and maximum 0.1% the aluminium, also contain the 0.5-2.0% cobalt, the nickel of 35.0-36.0%, the impurity of bringing into when balance iron and preparation.
Be lower than 0.5% cobalt contents and do not reach expected effect.Except containing nickel and cobalt, also contain maximum 0.009% carbon according to alloy of the present invention, maximum 0.1% manganese, the impurity of bringing into during the preparation of maximum 0.1% silicon and maximum 0.1% aluminium and minute quantity, surplus is an iron.Seem particularly outstanding according to alloy of the present invention with its significant processability, do not want additional method steps when producing shadow mask with it.This alloy has also shown the secular thermal characteristics stability corresponding to demand in addition.
Have less than 0.6 * 10 20-100 ℃ of temperature range according to alloy of the present invention
-6The very little thermal expansivity of/K.
The preferred embodiment of theme of the present invention obtains from the accessory dependent claims.So in order to satisfy desired requirement, preferably use nickel content to be 35.0-36.0%, cobalt contents is 0.7-1.3%, manganese content is maximum 0.05%, and silicone content is maximum 0.05%, and aluminium content is the iron-nickel alloy of 0.01-0.05%.The utmost point low thermal coefficient of expansion that can reach 20-100 ℃ of temperature range is about 0.4 * 10 like this
-6/ K.
According to general viewpoint, at least 0.2% higher manganese content is absolutely necessary for good thermal distortion.Even yet unexpectedly show according to alloy of the present invention also have extraordinary hot and cold deformability at low-down manganese content less than 0.05%.
This purpose also can reach by the iron-nickel alloy of using the low bulk performance, for the thermal expansivity of this alloy 20-100 ℃ of temperature range is adjusted to less than 0.6 * 10
-6/ K, except the carbon of (quality %) maximum 0.009%, maximum 0.1% manganese outside maximum 0.1% silicon and maximum 0.1% the aluminium, also contains the cobalt of 0.5-2.0% and the nickel of 35.0-36.0%, the impurity of bringing into when surplus is iron and preparation.This alloy not only can be used for
The shadow mask of-display screen and frame parts but also can be used for
The passive state composition of-hot pairing gold
-be used for the preparation of liquefied gas, store and the parts of transportation
-parts in laser technology.
