Description
Technical field
The invention belongs to field of functional materials, particularly relates to a kind of magnetic alloy powder material.
Background technology
In prior art, magnetic material particularly magnetic material is used as production high frequency transformer, magnetic head etc. to be needed to utilize
The product of magnetic material properties.Magnetic material refers to the magnetic material with demagnetization performance compared with permanent magnet material.Existing main magnetic
Property material production prepared with Ferrite Material substantially, the key property of this kind of Ferrite Material is that resistivity is high, high frequency whirlpool
The advantages of stream loss is little.But the saturation induction density of magnetic product prepared by the material is low, and temperature characterisitic is poor, is only capable of using
In temperature less than 100 DEG C of scope, when temperature exceedes this scope, its performance drastically declines even magnetic and disappears, therefore this
Class material is not suitable for the application under hot conditionss.
China's patent 20041002990 is provided and a kind of using FeCOMSiB alloy materials and improves the use of Co elements
Amount.Although the technical scheme can have higher temperature characterisitic, containing Co high magnetic alloy storage magnetic property and demagnetization speed not
Height, while CO belongs to narrow resources relative to China, import dependency degree is more than more than 90%, it is therefore necessary to which prior art is entered
Row is improved.
During metal smelt, to cool down through melting, the process such as reprocessing, complex procedures, and in each operation
In be required to consume substantial amounts of energy and also have the generation of harmful gass, through there is technology to produce using alloy powder die casting mode
Alloy product, so can be with
Content of the invention
The purpose of the present invention is by improvements over the prior art, in the temperature characterisitic and storage magnetic property that ensure magnetic material
And the demagnetization performance of this kind of magnetic material can be improved.
The present invention is achieved by the following technical solutions：
A kind of magnetic alloy powder material, the magnetic alloy material are FeCOMSiBTi base materials, and each composition composition is by original
Sub- percentage composition (at%) includes：The cobalt of 20-25, the M of 3-5, the silicon of 8-12, the boron of 10-15, the germanium of 1-3, the titanium of 1-3, remaining
For ferrum and a small amount of inevitably impurity；The M is one or more in copper and niobium, molybdenum, vanadium, zirconium of combination.
The atomic percentage conc (at%) of the copper is 0.8-1.2；One or more of combination in the niobium, molybdenum, vanadium, zirconium
Atomic percentage conc (at%) be 3-5.
Further improve, 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 preferable hot properties and storage magnetic property, is for making
The preferred magnetic material of magnetic head.
Further improve, described M is the combination of copper and vanadium.
Specific embodiment
Below in conjunction with specific embodiment so that the present invention is described in detail, select multigroup embodiment in this application and lead to
Cross the performance that the detection to each embodiment draws each component.
A kind of magnetic alloy powder material, the magnetic alloy material are FeCOMSiBTi base materials, and each composition composition is by original
