A kind of Co-Fe B alloy wires with mangneto twisting property high and preparation method thereof
Technical field
The invention belongs to field of magnetic material, it is related to a kind of Co-Fe B alloy wires with mangneto twisting property high and its system Preparation Method.
Background technology
, when magnetized state changes, the length and volume of its own occur small for ferromagnetism and ferrimagnetism material Change, this phenomenon is referred to as magneto-striction phenomenon.Ferrimagnet is subject to axial magnetic field Ha and Circumferential field Hc to act on simultaneously when, Material can be caused to produce a torsion, torsion angle is Φ, and this mangneto torsion phenomenon is referred to as Wertheim effect (Wiedemann effect).Wertheim effect and magnetostrictive effect are all a kind of magneto-mechanical effects of ferrimagnet.Since be found with Come, people think always be between them it is closely coupled, in other words Wertheim effect be exactly magnetostrictive effect one kind it is special Different situation, the material for possessing big magnetostriction generally also possesses big mangneto torsion.
Traditional ferrimagnet refers to pure Ni, Ni based alloy, Fe based alloys and Ferrite Material.With magnetostriction And the silk material of mangneto twisting property is widely used in the field such as liquid level sensor and displacement transducer.At present, open report Magnetostrictive displacement sensor (MDS) waveguide filament Fe-Ni alloy/C by saturation magnetostriction constant less than 30ppm mostly Silk, such MDS displacement detectings amount is no more than 5m (LuYun, Shen Rong, Feng Zhesheng, et al.Research on properties ofmagnetostriction Ni-Fe alloy for dis placement sensor[J] .Journal of Functional Materials,2009.40(11):1791-1793);And with Tb-Dy-Fe as representative Although giant magnetostrictive material should possess the larger mangneto coefficient of torsion in theory, with tensile strength is low, quality is more crisp not Easily it is prepared into mangneto and reverses silk material required during application.So, one kind has excellent mechanical performance easily prepared into silk material, The material but also with more greatly magnetostriction and mangneto twisting property is that pole has application prospect simultaneously.It is found that Fe-Ga There is alloy mechanical strength high and preferable plasticity to have the possibility for being processed into silk material, the Li Jiheng of China in 2010 Deng to Fe83Ga17Alloy has carried out directional solidification, hot-swage, hot pull, recovery and recrystallization heat treatment, obtains with good texture Fe-Ga B alloy wires, the B alloy wire saturation mangneto coefficient of torsion is about 245 " cm-1。(J.H.Li,X.X.Gao,T.Xia, L.Cheng,X.Q.Bao and J.Zhu.Texture Fe-Ga magnetostrictive wireswith large Wiedemann twist.J.Scripta Materialia.,2000,63:28-31.).Research finds that Co-Fe alloys have Magnetostriction coefficient higher (Dwight Hunter, Will Osborn, Ke Wang, Nataliya Kazantseva, Jason Hattrick-Simpers,Richard Suchoski,Ryota Takahashi,Marcus L.Young,Apurva Mehta,Leonid A.Bendersky,Sam E.Lofland,Manfred Wuttig&Ichiro Takeuchi.Giant magnetostriction in annealed Co1-xFex thin-films.Nature Communications,2010,2: 518), this has established theoretical foundation for Co-Fe alloys prepare high-performance magnetism to torsion and magnetostriction silk material.Compared to Fe-Ga First, Co-Fe cost of alloy is relatively reduced alloy;Secondly, Co-Fe alloys make it in silk with better plasticity, ductility Easier, efficient, energy-conservation on material process of preparing, can substantially reduce production cost;Finally, make compared with high-curie temperature Co-Fe B alloy wires can be applied in the hot environment being likely to occur.
