Description
Technical field
The invention belongs to field of magnetic material, relate to a kind of high-performance polycrystal texture magnetic deformation slice material and preparation method thereof.
Background technology
When being magnetized in the ferromagnet outside magnetic field, its length and volume all change, and this phenomenon is called as magnetostriction.Magnetostriction can be divided into line magnetostriction and volume magnetostriction.Practical magnetostrictive material promptly are meant the material with line Magnetostrictive Properties.The line magnetostriction performance of material is used (3/2) λ usually
sExpression, it has characterized a kind of magnetostrictive strain value of material intrinsic, can think accessible maximum magnetostriction strain value on the materials theory.In the practical application, the line magnetostriction coefficient represents with λ that usually λ=Δ L/L(L is the material original length, the variation that sample took place when Δ L was the magnetized state change).For flaky material, (3/2) λ
s=λ
//-λ
^, λ wherein
//Be meant that thin slice rolls to being parallel to the measured saturation magnetostriction coefficient of magnetic direction; λ
^Be meant that thin slice rolls to perpendicular to the measured saturation magnetostriction coefficient of magnetic direction.λ〉0 o'clock, be direct magnetostriction, ferromagnet extends along magnetic direction, and the vertical magnetic field direction shortens; When λ＜0, be negative magnetostriction, ferromagnet shortens along magnetic direction, and the elongation of vertical magnetic field direction.The maximum magnetostriction coefficient that material is produced when being magnetized is called the saturation magnetostriction coefficient lambda
s
Though traditional magnetostrictive material have the characteristics of Curie temperature height and good mechanical property, its magnetostriction coefficient is lower; And be though that the giant magnetostrictive material of representative has good performances such as magnetostrictive strain is big with Tb-Dy-Fe because its quality is more crisp, plasticity is very poor, poor in processability, the cost of raw material is more high, has limited the application of this material.
2000, people such as the Guruswamy S of the U.S. find that the Fe-Ga bianry alloy has the magnetostriction value more much higher than Fe-Al alloy, intensity is high more a lot of than giant magnetostrictive material with magnetic permeability, be a kind of novel magnetostrictive material with broad prospect of application, be called Galfenol, caused that the various countries researcher pays close attention to greatly.(Guruswamy?S，Srisukhumbowornchai?N，Clark?A?E，et?al．Strong,?ductile,?and?low-field-magntostrictive?alloys?based?on?Fe-Ga．Scripta.?Mater.，2000，43：239~244；Srisukhumbowornchai?N，Guruswamya?S．Large?magnetostriction?in?directionally?solidified?FeGa?and?FeGaAl?alloys．J.?Appl.?Phys.，2001，90(11)：5680~5688)。Though this material has magnetostriction performance preferably and mechanical property, because the resistivity of this material is lower, under high frequency, uses and can produce than the maelstrom loss, limited the application of this material.Therefore, people wish it to be rolled into laminar, to reduce the eddy current loss under the high frequency service condition, improve its high frequency characteristics.

In the above-mentioned research about Fe-Ga base sheeting, common deficiency is that manufacturing process is all too complicated, comprising need foundry alloy is carried out involucrum, hot rolling, all more than 100 passages, unidirectional saturation magnetostriction coefficient value of stress relief annealing repeatedly in the operation of rolling and gained thin slice is less for warm-rolling and cold rolling total passage.
At above-mentioned shortcoming, this research group is by optimizing alloying component, adopt simple relatively rolling mill practice to prepare Fe-Ga base sheeting, and obtained preferable performance by special thermal treatment technology (magnetic-field annealing, the recrystallization annealing of high vacuum high temperature secondary etc.) subsequently; But its heat treatment process is too complicated, the magnetostriction performance still remains to be improved, the rate of finished products of alloy not high disadvantages affect its commercial Application.The correlative study result successfully declares Chinese invention patent (patent No.: ZL 200910076722.4, publication number: CN101654759).
