Description

A kind of amorphous-nano-crystalline magnetically soft alloy and preparation method thereof
Technical field
The present invention relates to technical field of alloy, and in particular to a kind of amorphous-nano-crystalline magnetically soft alloy and preparation method thereof.
Background technique
Nineteen fifty-nine, professor Duwez of California Institute of Technology prepare amorphous alloy truly for the first time.Later, people Put into it is very big enthusiasm and energy, successfully prepared a series of amorphous alloys.Up to now, about share more than 2000 kinds it is non- Peritectic alloy system is developed in succession.Recently, simple substance Ta is also prepared to amorphous state.Amorphous alloy has not only deepened people to amorphous The scientific knowledge of state substance, and great engineer application potentiality are shown, because amorphous alloy has many crystal alloy can not The excellent properties of analogy, such as high elastic strain limit, yield strength, hardness, good fracture toughness, corrosion resistance, Wear resistance and catalytic, excellent soft magnet performance and thermoplastic forming etc..Nevertheless, amorphous alloy is due to glass shape Cause its critical dimension less than normal at ability is limited, while preparing the raw material and high vacuum environment of amorphous alloy palpus very high purity, Therefore high expensive, limits the industrial application of most of amorphous alloy system.
Fe base noncrystal alloy band is the amorphous alloy being most widely used at present, mainly due to its excellent soft magnetism Energy and the cheap prices of raw materials, while can produce in air, and beam thickness is generally less than 30 μm, therefore substantially not It is limited by glass forming ability.Fe base soft magnetic amorphous alloy band is primarily used for the first device of magnetism of electric power and electronics industry In part, such as transformer, inductor etc., market prospects are huge.The most commonly used Fe base soft magnetic stripe band is currently on the market 1K101 and 1K107, chemical component are Fe78B13Si9 (at.%) and Fe73.5B9Si13.5Nb3Cu1 (at.%).Due to 1K107 is amorphous-Nanocrystalline Two-phase structure, and the nano-crystalline granule and noncrystal substrate of precipitation have a very strong coupling, and this Kind coupling is not present in single-phase amorphous 1K101, enables the comprehensive magnetic ratio 1K101 of 1K107 more excellent It is different, therefore have higher degree of recognition on the market.However, containing Nb in 1K107 first, therefore the cost of raw material is higher；Its Secondary, nano-crystalline granule is by obtaining to the annealing that amorphous ribbon carries out in 1K107, i.e. 1K107's is prepared as two steps, first To single-phase amorphous ribbon, it is nanocrystalline that annealing precipitation is then carried out to it, therefore process flow is long, production efficiency is low, anneals simultaneously Process also increases energy consumption；Finally, annealing process embrittlement 1K107, band easily fragmentation cause to be stranded greatly very much to cutting, winding Difficulty reduces product yield.
Chinese patent CN102610348B discloses a kind of Fe-based nanocrystalline magnetically soft alloy material and preparation method thereof at present, Directly formed in rapid solidification by spinodal decomposition nanocrystalline, the general formula of the Fe-based nanocrystalline magnetically soft alloy material is Fe100-b-c-d-eCubAcBdCe, specific chemical analysis are (atom %): b=0.3-3%, c=2-8%, d=10-15%, E=2-15%, wherein A is at least one of Cr, V, Mo, W, Ta, Nb element, at least one of B Si, P element, C For at least one of C, B element.
But there is also high production cost for existing amorphous-nano-crystalline magnetically soft alloy preparation method, and energy consumption is high, and soft magnet performance is weak Defect.

For these problems, the present invention utilizes raw material Fe, Ni, the intermediate alloy Fe-Si and Fe-B of technical purity, is prepared in situ out one Serial Fe based amorphous-nano-crystalline soft magnetic stripe band alloy.The series alloy not only has excellent magnetic characteristics, and toughness is fabulous, substantially It solves the above problem, is successfully realized low cost, low energy consumption, high efficiency and high-performance, there is city more more extensive than 1K107 Field prospect.
In order to overcome the shortcomings of the prior art, the object of the present invention is to provide a kind of amorphous-nano-crystal soft magnetic alloys And preparation method thereof, effectively compensate for high production cost existing for the preparation method of existing amorphous-nano-crystalline magnetically soft alloy, energy Consumption is big, the weak defect of soft magnet performance.
In order to achieve the above purpose, it is achieved by the following technical programs:
A kind of amorphous-nano-crystalline magnetically soft alloy agglomeration resistance, the magnetically soft alloy ingredient are FeaNibBcSid, a, b, c, d are Atomic percent；
Wherein, 70-78%, b:2-12%, c:8-14%, d:2-6%；
Wherein, B and Si are respectively selected from ferro-boron and ferrosilicon.
The amorphous-nano-crystalline magnetically soft alloy the preparation method comprises the following steps:
It is first master alloy by raw material melting, then will be prepared into band using the method that the spray of single roller is got rid of after master alloy remelting Material.
Preferably, the beam thickness is about 24 μm, and width is about 2mm.
Preferably, the band is amorphous-nano-crystalline double structure, belongs to magnetically soft alloy band, saturation magnetization More than or equal to 170emu/g, coercivity is less than or equal to 20A/m.
Finally, investigating the microstructure of band using X-ray diffraction (XRD), it is found that Fe base band of the present invention is true The actually composite construction of amorphous-nano-crystalline；The thermodynamic characteristics temperature of band is determined using differential scanning calorimetry (DSC)；Benefit The saturation magnetization of band, while rectifying using coercivity instrument measurement band are obtained with vibrating specimen magnetometer (VSM) measurement Stupid power.Table 1 is the performance characteristic parameter of three exemplary samples in the present invention.
Using above-mentioned technical solution, beneficial effects of the present invention are as follows:
Firstly, raw material be common Fe, Ni and intermediate alloy Fe-B and Fe-Si, the rare metal without containing such as Nb, Therefore the cost of raw material is reduced；Secondly, the double structure of amorphous-nano-crystalline is generated in-situ, nanometer during getting rid of band Brilliant particle is precipitated not by high annealing, therefore not only increases production efficiency, and reduces energy consumption；Finally, of the invention Fe based amorphous-nano-crystalline band not only there is excellent soft magnet performance, and there is good toughness, be conducive to it is subsequent plus Work, so help to improve the yield of final products.
