Description
Technical field
The invention belongs to metal material field, more particularly to a kind of temperature range wide, the magnetic temperature compensating alloy of high linearity.
Background technology
Eighties of last century twenties can be traced back to for the research of pyromagnetic compensator alloy, nineteen twenty-eight, A.Z.Kussmann was reported
The magnetic strength of Monel alloys drastically changes near Curie temperature with temperature, and the same period, Germany occurred in that ambrose alloy iron system Calmalloy types
Alloy, by the Alloyapplication in self-compensated temperature indicator, F.Steblein is reported nineteen thirty I.F.Kinanard within 1934
The temperature effect of the iron nickel system Thermoperm alloy magnetic induction intensity of nickel content 31%.
Magnetic temp compensating Material Field has formed more perfect series of products, and it is big that pyromagnetic compensator alloy presses alloy system
Cause can be divided into ambrose alloy system, iron nickel system, iron nickel manganese systems, iron nickel aluminium series and iron nickel chromium triangle system, and wherein ambrose alloy system and iron nickel system belongs to higher
Magnetic induction and the alloy compared with high-Curie-point.The nickel copper series alloy of early development is (close to 70%) too high due to nickel content, with magnetic
Induction is low, compensation temperature range is narrow, it is expensive the shortcomings of, replaced by the iron nickel system alloy of low nickel-content at present.
Pyromagnetic compensator alloy more common both at home and abroad is simple iron nickel system bianry alloy at present, and particularly nickel content is 30% or so
Iron-nickel alloy.
Iron nickel magnetic temperature compensating alloy is that the characteristics of it is protruded is magnetic induction intensity value using a kind of most thermal-magnetizing materials
Height, and production cost is relatively low, the alloy dosage used under similarity condition is less.But the magnetic of this simple ferrous nickel bianry alloy
Can be quite sensitive to the content of Ni, so generally reducing this sensitiveness using the come from different backgrounds and possess different abilities method of alloy of addition new constituent element
(Cr contents 12.5~13.5% in such as 1J38).
In the magnetic temperature compensation of the existing trade mark, there are 1J30,1J31,1J32,1J33,1J38 etc., but their compensation temperature
Degree scope is narrower, generally -20 DEG C~+60 DEG C, and 1J33 is -20 DEG C~+80 DEG C, and its compensation gradient is also each different, therefore its
The scope of application can be subject to certain restrictions, external import since the material of current ultralow temperature is main, there is high cost.
The content of the invention
It is an object of the invention to provide a kind of temperature range wide, the magnetic temperature compensating alloy of high linearity.The alloy has temperature wide
Compensation (- 60 DEG C~+85 DEG C), and the linearity is good, and have the pyromagnetic compensator alloy of certain gradient, can meet in high/low temperature work
Operating temperature range and the requirement of the B-T slopes of curve in environment.
The technical scheme is that：
The magnetic temperature compensating alloy of temperature range wide, high linearity, the weight percentage of each component is：Cr1.2~2.4%,
Ni30~30.7%, Mn≤0.4%, impurity element≤0.016%, balance of Fe.
The above-mentioned preferable technical scheme of alloy is that the weight percentage of each component is：Cr1.4~2.3%, Ni30.2~
30.5%th, Mn≤0.4%, impurity element≤0.016%, balance of Fe.
The impurity element is C, S, P.
The weight percentage of the impurity element each component is C≤0.01%, S≤0.003%, P≤0.003%.
The preparation method of alloy of the present invention is as follows：
Alloy of the present invention uses vacuum induction melting, then obtains alloy pig by electroslag remelting.Alloy by hot forging,
Hot rolling, solution treatment is cold-rolled to finished product, is used after final annealing, and its B-T curve is as shown in Figure 1.
The solution have the advantages that：
Compared with existing same type high performance alloys, alloy of the present invention is with the same of the good magnetic compensation linearity
When, it may have broader temperature in use interval (- 60 DEG C~+85 DEG C), relative to the magnetic temperature compensating alloy of current domestic production,
It uses scope more extensive, it is adaptable to the low temperature environment less than -20 DEG C, and it specifically compensates performance and can solve the problem that current ultralow temperature
The problem of external import material is relied in environment, and has the advantages that low production cost.
(1) chemical composition of alloy of the present invention had both ensured the excellent magnetic compensation linearity by well-designed, protected again
Certain magnetic compensation performance is demonstrate,proved.
(2) addition of non-ferromagnetic elements Mn, can make the work magnetic induction intensity of alloy reduces, therefore is added in alloy suitable
The element M n of amount, can play a part of to adjust the work magnetic induction intensity of alloy.
(3) addition of Cr elements, the magnetic property to alloy also has a certain impact.In control range, with Cr contents
Increase, B-T slope of a curves gradually increase, but the work magnetic induction that Cr too high levels can equally substantially reduce alloy is strong
Degree, Cr contents are too low, cannot obtain preferable magnetic compensation gradient, therefore Cr contents need to control in the range of 1.2~2.4%.
(4) because the magnetic property of alloy is very sensitive to Ni contents, the work of Ni contents higher (or relatively low) then alloy
Magnetic induction intensity can be raised drastically (or reduction), therefore to obtain appropriate magnetic property, the Ni constituent contents of alloy are strict
Control is in the range of 30~30.7%.
(5) content of the harmful element such as other C, P, S will be controlled strictly, and the content of impurity is lower, and the magnetic property of alloy is got over
It is good.
Applicant is by experimental verification, and the performance of alloy of the present invention is as follows：
1. the temperature in use scope of alloy is -60 DEG C~+85 DEG C.
The magnetic compensation performance of alloy：
In temperature in use is interval, mT/ DEG C of dB/dT=- (5.6 ± 0.8), and B-60℃/B85℃：>=7, the typical case of alloy
B-T curves are as shown in Figure 2.
