Abstract
The invention relates to a Fe-Ga group magnetostriction wire and material composition thereof is Fe1-x-yGaxMy, wherein, M is tantalum of transition group except for Fe and one or a plurality of Be, B, Al, In, Si, Ge, Sn, Pb, Sb, Bi, N, S and Se; x is equal to 5-30at percent and y is equal to 0-15at percent and the allowance is Fe; diameter d is 0.1-5mm. A device adopts the Fe-Ga group magnetostriction wire is also disclosed.
Description
Technical field
The invention belongs to field of magnetic material, relate to a kind of Fe-Ga base magnetic striction wire, this material can be as the senser of devices such as transducer.
Technical background
When magnetostrictive material are placed the external magnetic field of certain orientation, the spontaneous magnetization direction of material magnetic domain will turn to outer magnetic field direction, if magnetic domain is different with the dimension of other direction along the dimension of spontaneous magnetization direction, strain will take place, and then generation stress, from macroscopic perspective, material changes along the yardstick of external magnetic field, i.e. joule (Joule) effect, also can cause the variation of material magnetic flux density when otherwise the material magnetic domain direction changes under the effect of stress, be referred to as Villari (Villari) effect or joule back wash effect or magnetostrictive reaction.When the alternating magnetic field of certain intensity that superposes along outer magnetic field direction, magnetic domain direction also can be done with changing frequently with external magnetic field, produce alternate stress at material internal, at this moment strain is propagated in material under the effect of alternate stress and is formed compressional wave, its back wash effect can be used for receiving compressional wave, except the longitudinal extension effect, on plane, apply the toroidal magnetic field and will form helical magnetic field perpendicular to external magnetic field, the magnetostrictive material vibration that can twist, produce torsional wave, be called Wiedemann (Wiedemann) effect, corresponding Wiedemann back wash effect also claims uncommon (Matteuci) effect of Manta also torsional wave can be converted to the variation of magnetic flux density.
Utilize Wiedemann (Wiedemann) effect, magnetostrictive material can be processed into the senser of a material (being magnetic striction wire, magnetostriction line or waveguide filament) as devices such as displacement transducer, magnetoelasticity type torque sensor, Young's modulus transducers, and they can convert input variable to can be for the signal of measuring.This class transducer plays an important role in fields such as quality inspection, optimal control, monitoring of working condition and failure diagnosises.Though the Terfenol alloy has very big magnetostriction value, its character is very crisp, is difficult to be processed into a material.At present the waveguide filament of using mainly is Fe-Ni base alloy silk, amorphous alloy wire, but their magnetostrictive reaction a little less than, the sensitivity and the precision of influence test.
It is found that recently there is higher magnetostriction coefficient (0.02%~0.03%) in the Fe-Ga alloy, and saturation magnetic field has only 15920~23880A/m; In addition,, ductility and machining property are preferably arranged, can be processed into the shape of various complexity because the Fe-Ga alloy is a metal solid solution; And this alloy also has good temperature characterisitic, can use in very wide temperature range.Utilizing Fe-Ga alloy designs device, or the sensitivity of product is increased substantially, or make the miniaturization of products, or conventional art can not obtainable function be achieved, is a kind of new material that has market potential.High-quality Fe-Ga magnetic striction wire owing to have above-mentioned excellent characteristic, is used for the senser of magneto strictive sensor, can improve the sensitivity and the precision of transducer greatly.
