Abstract
The invention relates to a magnetic powder alloy material, which is the basic material of FEC0MSiBTi, wherein each of constituted components comprises by atom percent (at %): 20 to 25 percent of cobalt, 3 to 5 percent of M, 8 to 12 percent of silicon, 10 to 15 percent of boron, 1 to 3 percent of titanium, 1 to 3 percent of scandium and 1 to 3 percent of ruthenium, and the rest percent is iron and few amount of inevitable impurities; 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 magnetic powder alloy material especially.
Background technology
In prior art, magnetic material particularly magnetic material is used as producing high frequency transformer, magnetic head etc. and needs to utilize the product of magnetic material properties.Magnetic material refers to that the magnetic material with demagnetization performance compared by same permanent magnetic material.The now production of main 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 magnetic product 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.
In metal smelt process, through melting, cooling, the processes such as reprocessing, complex procedures, and all need to consume the generation that a large amount of energy also has pernicious gas in each operation, technology has now been had to adopt alloy powder die casting mode to produce alloy product, passable like this
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 magnetic material in the temperature characterisitic and storage magnetic property that ensure magnetic material.
The present invention is achieved by the following technical solutions:
A kind of magnetic powder alloy material, described magnetic alloy material is FeCOMSiBTi base material, each composition composition comprising by atomic percentage conc (at%): the cobalt of 20-25, the silicon of the M of 3-5,8-12, the boron of 10-15, the titanium of 1-3, the scandium of 1-3%, the ruthenium of 1-3%, all the other are iron and a small amount of inevitably impurity; Described M is one or more combination in 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.
Further improvement, described M is the combination of copper and vanadium.
The invention has the beneficial effects as follows:
Compared with the existing technology, this magnetic material alloy has good hot properties and storage magnetic property, is the preferred magnetic material for making magnetic head.
Further improvement, described M is the combination of copper and vanadium.

A kind of magnetic powder alloy material, described magnetic alloy material is FeCOMSiBTi base material, each composition composition comprising by atomic percentage conc (at%): the cobalt of 20-25, the silicon of the M of 3-5,8-12, the boron of 10-15, the titanium of 1-3, the scandium of 1-3%, the ruthenium 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.
Described M is the combination of copper and vanadium.
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 magnetic material rolling up cobalt content in prior art, but cost reduces in a large number.
