A kind of method utilizing column crystal slab to prepare orientation magnetostriction thin plate
Technical field
The invention belongs to field of magnetic material, relate to and utilize column crystal slab to prepare the magnetostriction thin plate preparation method with high preferentially <001> orientation.
Background technology
Ferromagnetism and ferrimagnetic material are when magnetized state changes, and the length of himself or volume minor variations can occur, and this phenomenon is called magnetostriction.The change of volume is called volume magnetostriction, and the change of length is called line magnetostriction.Because volume magnetostriction change is very little, practical value is not high, and usually said magnetostriction mainly refers to line magnetostriction.
Magnetostriction materials, as the one of intellectual material, are widely used in transducing, driving and field of sensing technologies.High-power magnetostrictive transducer all has wide practical use in national defence and civilian modern industry field, and its core is exactly big magnetostriction coefficient material.Due to metal material low-resistivity, under action of alternating magnetic field, can generate heat because of eddy-current loss, not only reduce the energy efficiency of device, also likely cause material failure because of heating.Therefore, high-power magnetostrictive transducer, needs to have excellent mechanical performances, can process again sheet high-magnetostriction performance materials simultaneously.Although rare earth ultra-magnetostriction material Tb-Dy-Fe has big magnetostriction performance, fragility is large, is difficult to be processed into thin slice; Although the mechanical properties such as tradition magnetostriction alloy Fe-Ni, Ni, Fe-Al are good, magnetostriction coefficient is low, is difficult to meet high power requirements.
2000, people (the S.Guruswamy such as U.S. S.Guruswamy, N.Srisukhumbowornchai, A.E.Clark, J.B.Restorff, M.Wun-Fogle.Srong, Ductile, and Low-Field-Magnetostrictive Alloys Based on Fe-Ga, Scripta mater.43 (2000) 239 – 244) report Ga and substitute Al in Fe-Al alloy, obtain Fe-Ga or Fe-Ga-Al alloy, not only there is high Magnetostriction, there is good mechanical performance simultaneously, the requirement of high-power magnetostrictive transducer to material can be met.But Fe-Ga or Fe-Ga-Al alloy, also due to its low-resistivity, also needs to be processed into thin slice, effectively could avoid the eddy-current loss of material under alternating magnetic field.Meanwhile, due to magnetostrictive anisotropy, need along board rolling direction, to there is <001> orientation, the Magnetostriction that guarantee is maximum, namely usually require that rolling strip has Gauss or cubic texture.
Document (N Srisukhumbowornchai, S Guruswamy.Crystallographic textures in rolled and annealedFe-Ga and Fe-Al alloys.Metall.Mater.Trans.A, 2004,35A:2963) report add NbC in Fe-Ga or Fe-Al alloy, prepare magnetostriction thin plate by hot rolling, warm-rolling and cold rolling method, after high-temperature process, obtain Gauss or cubic texture.Document (S M Na, A B Flatau, Surface-energy-induced selective growth of (001) grainsin magnetostrictive ternary Fe – Ga-based alloys, Smart Mater.Struct.21 (2012) 055024) report the Fe-Ga thin plate that the method acquisition utilizing surface energy to induce has strong Gauss's orientation, there is comparatively high-magnetostriction performance.Chinese patent (CN101465406B) discloses by one or more in interpolation B, Nb, Cr, TiC, VC, MnS, AlN, and one or more in S, Sb, Sn, by the control of rolling and Technology for Heating Processing, obtain and there is obvious cube or goss texture, there is the Fe-Ga latten of big magnetostriction performance simultaneously.
, there is material rolling processing technology complicated in the above-mentioned preparation method about magnetostriction thin plate, magnetostriction sheet band orientation is unstable, causes the problems such as magnetic property is not high.
Summary of the invention
The object of this invention is to provide the column crystal strand that a kind of utilization has <001> orientation, by rolling and subsequent heat treatment, obtain the magnetostriction thin plate process technology obviously with preferentially <001> orientation.
The present invention controls from continuous casting billet structure, by the technique that directed pouring technology or common cast are combined with directional solidification, obtain the hot rolling slab with preferred orientation, then by hot rolling, warm-rolling and cold rolling, rolling temperature control and drafts, avoid or reduce the recrystallization in rolling deformation process, retain the deformed microstructure of former preferred orientation column crystal, obtain the rolling strip with preferred orientation finally by heat treatment, make rolling mill practice process simplification, there is prospects for commercial application.
Utilize column crystal slab to prepare a method for orientation magnetostriction thin plate, alloying component (by atomic percentage), is expressed as: (Fe 100-x-yga xal y) 100-zm z, wherein x=10 ~ 25, y=0 ~ 9; M is one or more in B, Nb, Cr, Sn, MnS, NbC, VC, TiC, z=0 ~ 1.0; Surplus is iron.
High-performance magnetostriction thin plate preparation method, concrete technology flow process is as follows:
The one that the column crystal slab with preferentially <001> orientation is chosen in following two kinds of methods realizes:
Method one: according to alloying component proportioning; and add appropriate scaling loss; under argon shield, induction melting is to after completely evenly, is poured in proper mold, mold bottom chilling; make bottom alloy liquid rapid solidification; remainder high-temperature heating, alloy liquid keeps molten state, and downward pull promotes column crystal growth; obtain <001> preferred orientation, drawing velocity size 1 ~ 20mm/min.
Method two: according to alloying component proportioning, and add appropriate scaling loss, under argon shield, induction melting is to after completely evenly, is poured into common die, forms alloy pig.Utilize apparatus for directional solidification, carry out alloy pig remelting, control the column crystal direction of growth by the size of withdrawing rate, obtain <001> preferred orientation, withdrawing rate is at 0.05 ~ 15mm/min.
To the column crystal slab with preferentially <001> orientation, carry out hot rolling, warm-rolling and cold rolling along the column crystal direction of growth.Slab thickness 5 ~ 100mm, directly can use column crystal slab or from column crystal slab, cut the suitable slab needing thickness.Strict control hot rolling open rolling and finishing temperature, start rolling temperature 950 ~ 1200 DEG C, drafts 60 ~ 97%, finishing temperature, lower than 850 DEG C, is quickly cooled to room temperature; Warm-rolling temperature at 350 ~ 600 DEG C, warm-rolling drafts 40 ~ 90%; After the pickling of warm-rolling plate, carry out cold rolling, to the thickness needed, between final thickness 0.05 ~ 0.5mm.
