Abstract
The invention relates to a magnetically soft alloy, which is the basic material of FeCOMSiBTi, wherein each component comprises by atom percent (at %): 25-30 percent of cobalt, 3-5 percent of M, 8-12 percent of silicon, 10-15 percent of boron, 5-8 percent of titanium and 1-3 percent of scandium, and the rest percent if iron and few amount of inevitable impurities; and the combination is M copper and one or more of niobium, molybdenum, vanadium, and zirconium.
Description
Technical field
The invention belongs to field of functional materials, refer to a kind of magnetically soft alloy especially.
Background technology
In prior art, soft magnetic material is used as the product that production high frequency transformer, magnetic head etc. need to utilize soft magnetic material characteristic.Soft magnetic material refers to that the magnetic material with demagnetization performance compared by same permanent magnetic material.The now production of main soft magnetic material is prepared with Ferrite Material substantially, and the key property of this kind of Ferrite Material is the advantages such as resistivity is high, and high frequency eddy current losses is little.But the saturation induction density of soft magnetic products prepared by this material is on the low side, temperature characterisitic is poor, only can be used in temperature lower than the scope of 100 DEG C, when temperature exceedes this scope, its performance even magnetic that sharply declines disappears, and therefore this kind of material is not suitable for the application under hot conditions.
China's patent 20041002990 provides a kind of FeCOMSiB of employing alloy material and improves the consumption of Co element.Although this technical scheme can have higher temperature characterisitic, the magnetic alloy storage magnetic property high containing Co and demagnetization speed not high, simultaneously CO belongs to narrow resources relative to China, and import dependency degree, more than more than 90%, is therefore necessary to improve prior art.
Summary of the invention
The object of the invention is by improvements over the prior art, also can improve the demagnetization performance of this kind of soft magnetic material in the temperature characterisitic and storage magnetic property that ensure soft magnetic material.
The present invention is achieved by the following technical solutions:
A kind of magnetically soft alloy, described magnetically soft alloy material is FeCOMSiBTi base material, and each composition composition comprising by atomic percentage conc (at%): the cobalt of 25-30, the silicon of the M of 3-5,8-12, the boron of 10-15, the titanium of 5-8, the scandium of 1-3%, all the other are iron and a small amount of inevitably impurity; One or more combination in described M copper and niobium, molybdenum, vanadium, zirconium.
The atomic percentage conc (at%) of described copper is 0.8-1.2; The atomic percentage conc (at%) of one or more combination in described niobium, molybdenum, vanadium, zirconium is 3-5.
The invention has the beneficial effects as follows:
Compared with the existing technology, this soft magnetic alloy has good hot properties and storage magnetic property.
Embodiment
Below in conjunction with specific embodiment so that the present invention is described in detail, select many group embodiments also by drawing the performance of each component to the detection of each embodiment in this application.6 groups of embodiments are selected in this application altogether.
A kind of magnetically soft alloy, described magnetically soft alloy material is FeCOMSiBTi base material, and each composition composition comprising by atomic percentage conc (at%): the cobalt of 25-30, the silicon of the M of 3-5,8-12, the boron of 10-15, the titanium of 5-8, the scandium of 1-3%, all the other are iron and a small amount of inevitably impurity; One or more combination in described M copper and niobium, molybdenum, vanadium, zirconium.
The atomic percentage conc (at%) of described copper is 0.8-1.2; The atomic percentage conc (at%) of one or more combination in described niobium, molybdenum, vanadium, zirconium is 3-5.
The preparation of embodiment carries out melting in vaccum sensitive stove, is first evacuated to 10 by stove
-3more than Pa; then be filled with 1 atmospheric argon gas, melting is in employing argon shield and is cast into alloy base substrate after sufficient electromagnetic agitation, then is carried out according to need by base substrate being processed into semi-finished product; again through 500-520 DEG C and the insulation annealing of 30 minutes, then to product test.
The testing experiment of product
The measurement of magnetic permeability Bs (T) is 10 in vacuum degree
-3carry out in Pa vacuum furnace, metering system employing heating rate is that the linear temperature increase of 3.5 DEG C/min is measured.Through measuring, the technical program has good temperature characterisitic.
The concrete composition of embodiment 1-6 is in table 1
Composition (table 1) the unit atomic percent at% of various embodiments of the present invention
Can be shown by above measurement result, technical scheme of the present invention is similar with the performance of the soft magnetic material rolling up cobalt content in prior art, but cost reduces in a large number.
