Description
Technical field
The present invention relates to novel magnetic materials, belong to field of functional materials.
Background technology
With the development of science and technology, magnetic alloy in electric power, electronics, computer, automatically control and the emerging technology such as electrooptics
In field, there is increasingly extensive application.Magnetic material can be divided into soft magnetic material and hard magnetic by the difficulty or ease of degaussing after magnetization
Material.Easily remove the material of magnetic soft magnetic material after magnetization, it is not easy to which the material of degaussing is retentive material.It is general next
Say that soft magnetic material remanent magnetism is smaller, retentive material remanent magnetism is larger.
Wherein, soft magnetic materials is often used as producing the product with soft magnetic characteristic such as high frequency transformer, choke coil and magnetic head.
Existing soft magnetic materials mainly uses ferrite material for matrix to prepare, and there is such material resistivity height, high-frequency vortex to damage
The advantages of consuming small.But, because the saturation induction density of material is relatively low, temperature characterisitic is poor, and its Curie temperature is 450 DEG C of left sides
The right side, under the high temperature conditions, the performance of material drastically decline even magnetic and disappeared, and therefore, this kind of material is not suitable for making under high temperature
With.
For disadvantages described above, this area scientific research personnel has done substantial amounts of research.At present, a kind of conventional method is in alloy
Middle addition Co elements, change the high temperature magnetic characteristic of material using α-FeCo, it is still had at a higher temperature preferable
Magnetic.
Such as, to disclose a kind of high temperature that can be used at high temperature non-for the patent of invention of Application No. 200410029900.5
Brilliant, microcrystalline soft magnetic alloy material, using FeCoMSiB as base material, the alloy employs 10~60% Co elements, has at high temperature
There is very high high temperature soft magnetic characteristic.
The patent of invention of Application No. 201611077360.7 discloses a kind of magnetic alloy powder material, with
FeCoMSiBTi is base material, and the alloy employs 20~25% Co, is to be used for preferable hot properties and storage magnetic characteristic
Make the preferred magnetic material of magnetic head.
Above patent is that the soft magnetic characteristic under high temperature is improved by adding Co.But, because metal Co belongs in China
In narrow resources, largely dependent on import, therefore, Co prices are higher, and substantial amounts of metal Co contents are added in the alloy, undoubtedly can
Substantial increase prepares cost so that the alloy can not be applied to industrialized production.
Therefore, a kind of lower-cost resistant to elevated temperatures novel magnetic alloy material is needed badly.
The content of the invention
For disadvantages described above, present invention solves the technical problem that being to provide a kind of inexpensive novel magnetic materials, the material
Material still has preferable magnetic under the high temperature conditions.
