Technical field

The invention belongs to magnetic metal material preparation technical field, in particular to the high saturation of a kind of high ferromagnetic constituent content Magnetic induction intensity Fe-based amorphous alloy and preparation method thereof.

Background technique

For crystal alloy, have atom in longrange disorder by the amorphous alloy that quick setting method is prepared The structure feature of arrangement, this special structure feature make it have unique mechanical property, magnetic property, corrosion resistance and electricity Learn performance etc..So far, researcher has successfully researched and developed and has prepared the amorphous alloy of a variety of different systems, including The amorphous alloys system such as Pd-, Zr-, Mg-, Zn-, Al-, Co-, Fe-, Ln-, Cu-.It is iron-based non-in these amorphous alloy systems Peritectic alloy is resourceful, cheap for other amorphous alloy systems, is provided simultaneously with high intensity, high rigidity, corrosion resistant The features such as erosion, good soft magnet performance, thus be concerned.Iron base amorphous magnetically-soft alloy strip has obtained industrially scalable and has answered With 1K101 amorphous alloy (Fe₇₈B₁₃Si₉, U.S. trade mark METGLAS 2605SA1) and it has been largely used to manufacture transformer core, and Nanometer crystal alloy (the 1K107 alloy, i.e. Fe obtained after crystallization_73.5Si_13.5B₉Nb₃Cu₁Nanometer crystal alloy, the international trade mark Finement manufacture mutual inductor, common mode inductance iron core etc.) are also largely used to.Also, the application of Fe-based amorphous/nanometer crystal alloy Field is also constantly expanding, and has a extensive future.

Iron base amorphous magnetically-soft alloy is mainly used to substitute traditional silicon steel magnetically soft alloy, manufactures various iron cores.Although it is full And magnetic induction density B_sBe not it is very high, such as the saturation induction density about 1.56T of 1K101, be less than silicon steel magnetically soft alloy and be saturated magnetic Induction (B_s=1.8-2.1T), but it has many advantages, such as that coercivity is low, magnetic conductivity is high, resistance is high, iron loss is small, while amorphous Alloy strip has the characteristics that preparation process flow is short.The country such as the U.S., Japan, Germany, China is big by AMORPHOUS ALLOY RIBBONS Measure the soft magnetic materials iron cores such as the iron core for being used to prepare transformer and other induction coil iron cores.It is prepared and is become using Fe-based amorphous alloy Depressor iron core has obtained large-scale popularization because having many advantages, such as that processing technology is simple, loss is low, small in size, high-efficient and has answered With.And Sol-Gel alloy can substitute cobalt base amorphous alloy, crystalline state permalloy and ferrite, in high-frequency power electronic and It is applied widely in electronic information field, reaches and reduce volume, reduce the purpose of cost that (Yao Kefu etc., iron-based soft magnetic is non- Crystalline substance/nanometer crystal alloy progress and application prospect, " Acta Physica Sinica " 2018,67,016101).However Fe-based amorphous alloy pair The requirement of preparation condition is more harsh, and cooling velocity need to reach about 10⁵K/s or more, common single-roller method gets rid of band or double roller gets rid of band method About 20-40 μm of thickness of alloy thin band is prepared, the big band of thickness is difficult to obtain pure amorphous alloy material.In order to improve Fe base The amorphous formation ability of alloy system need to add element (the also known as vitrifying for improving amorphous formation ability by alloyage process Element or decrystallized element), researcher successfully has developed a series of amorphous alloys such as Fe-B, Fe-Si-B, Fe-P-C accordingly Material.Although its vitrifying Forming ability can be improved in addition vitrifying formation element, but these vitrifying formation elements are to iron The replacement of element causes the magnetic performance of alloy system to deteriorate, especially saturation induction density B_sIt reduces.And improve Fe element Low-alloyed amorphous formation ability can drop in content again, make it difficult to prepare amorphous alloy.Thus within considerable time, The Fe content of most Fe-based amorphous alloys of research and development and application is below 81at.%.Obviously Fe content is improved, exploitation has Higher amorphous formation ability, high saturated magnetic induction, excellent comprehensive soft magnet performance new iron-based amorphous alloy have it is important Meaning and practical value.Recent years, researcher increase grinding for high Fe content (Fe >=81at.%)

B_sRespectively up to 1.64T and 1.67T (Ogawa Y, Naoe M, Yoshizawa Y, Hasegawa R, 2006J Magnetism and Magnetic Materials 304e675).The study found that compared to saturation Magnetic induction intensity is the 1K101 amorphous alloy of 1.56T, this high B_sAmorphous alloy 50Hz, 1.4T work magnetic strength under the conditions of Loss value reduces 15%.There is higher B_sLoss lower (Makino of the HB1 amorphous alloy under identical operating condition A, Kubota T, Chang C, Makabe M, Inoue A 2007Materials Transactions 483024).This grinds Study carefully the great attention that result causes to go together both at home and abroad.Although there are still many problems in industrialization, this shows do not adding Under conditions of the precious metal elements such as Co, the saturation induction density of iron-based soft magnetic amorphous alloy still can further improve.2009, Makino and Men He et al.^[30-31]Have developed Fe-Si-B-P-Cu system (Makino A, Men H, Kubota T,

Performance: Fe_84-x-yCu_xNb_ySi₄B₁₂、Fe_84-xSi₄B₈P₄Cu_x(2013 Journal of of Fan X, Men H, Ma A, Shen B Magnetism and Magnetic Materials 326 22)、Fe₈₁Mo₁P_7.5C_5.5B₂Si₃(Liu F J, Yao K F, Ding H Y 2011Intermetallics 19 1674)、Fe₈₂Si₄B₁₀P₂Cu₁Nb₁(Xiang Z, Wang A, Zhao C, Men H, Wang X, Chang C, 2015 Journal of Alloys and Compounds 622 1000), Fe₈₅Si₂B₈P₄Cu₁(2015 Scripta Materialia 95 of Sharma P, Zhang X, Zhang Y, Makino A 3), Fe_84.3Si₄B₈P₃Cu_0.7(Jafari S, Beitollahi A, Yekta B E, Ohkubo T, Budinsky V, Marsilius 136) etc. M, Herzer G, Hono K, 2016Journal of Alloys and Compounds 674.But these

or 4 elements are contained only.Alloy containing five elements of FeBCSiP or simultaneously Less (the Fe of amorphous alloy containing tetra- nonmetalloids of B, C, Si, P₈₁Mo₁P_7.5C_5.5B₂Si₃, Liu F J, Yao K F, Ding H Y 2011 Intermetallics19 1674).In a few studies containing 5 elements or four nonmetalloids In work, general phosphorus content is lower, contains Si higher, to improve amorphous formation ability.And contain five constituent element of FeSiBPC in minority In alloy, the content of P element is usually higher, and general P content is much in 3at.%, to improve amorphous

formation ability and preferably Soft magnet performance, need carry out go deep into theory analysis and lot of experiments.Inventor is long-term theoretical and experimental study sum On the basis of, although discovery P element addition advantageously reduces coercivity, saturation induction density can be also reduced, C and B are certain Be conducive to increase saturation induction density in degree.Atom is in disorderly arranged, average atom semidiameter and knot in amorphous alloy Structure and amorphous formation ability are directly linked, and research finds saturation induction density and average atom in high Fe content amorphous alloy There are positive correlations for semidiameter.In addition, Si member procatarxis and C, P, B have the larger negative heat of mixing, therefore it will affect average atom radius Difference, and influence the saturation induction density (not delivering result in laboratory) of alloy.In the base of lot of experiments and theory analysis On plinth, the invention proposes with high saturated magnetic induction, low-coercivity, low iron loss FeBCSiP, FeBCSiPM, FeCoBCSiP, FeCoBCSiPM ferrous alloy system.Compared with existing report result, in alloy system proposed by the present invention, dash forward Out feature be increase C content, reduce P and Si content, and rationally designed B, C, Si, P element relative
