Before being heat-treated, its internal structure is in unordered state to Fe-based amorphous material, now non-crystalline material
It is stable, it is impossible to inspire the soft magnet performance of material, the loss of material is larger；And Fe-based amorphous material is by this programme
Heat treatment process in, after a certain temperature is reached, crystallinity increases with the rising of temperature, non-crystalline material internal structure
More in order, crystallinity increase, the quantity of electric charge increase that unit area passes through, electric current increase, therefore, by after this programme heat treatment
Fe-based amorphous material with the rising of temperature, Fe-based amorphous material crystalline degree increase, electric current increase, energy loss reduces.Iron
The main component of base non-crystalline material is iron, silicon, boron, and its inductance is the superposition of multiple materials, therefore, the inductance of Fe-based amorphous material
Increase compared with the inductance of silicon steel sheet in the prior art.
Comparative example 1：It is with place of the difference of embodiment 1, the same size inductance coil made using current material,
In the case of frequency, voltage constant, inductance and curent change are tested.
Comparative example 2：Difference part with embodiment 1 is to be filled with nitrogen in the vacuum chamber.
The inductance coil that Fe-based amorphous material after being processed through above-mentioned heat treatment method in embodiment 1-9 is made, and it is right
Ratio 1-2, in the case of frequency, voltage constant, inductance is as follows with the test data of electric current：
Test data 1：Frequency：100HZ voltages：0.3V units：Electric current (A), inductance (uH)
Test data 2：Frequency：1KHZ voltages：0.3V units：Electric current (A), inductance (uH)
Test data 3：Frequency：10KHZ voltages：0.3V units：Electric current (A), inductance (uH)
As above table as can be seen that Fe-based amorphous material obtained by the method treatment of comparative example 1 and embodiment 2-9
Material, there is some difference for the crystallinity change of material internal, non-using iron-based from overall data in applying to inductance coil
The coil that brilliant material makes, inductance increases with the increase of electric current, the Fe-based amorphous material after detecting that embodiment 1-9 is processed
The soft magnet performance of material, testing result shows that the soft magnet performance of embodiment 1 is comparatively stablized.It can be seen that temperature is non-to iron-based
The soft magnet performance and mechanical property of brilliant material have large effect, and excellent soft magnet performance only has by suitable heat treatment rear
Can manifest, in the case that temperature is relatively low, it is impossible to inspire the soft magnet performance of material, the loss of material is larger, and at embodiment 1
Fe-based amorphous material after reason, input inductance coil can effectively reduce the damage of Fe-based amorphous material by test in the middle of
Consumption, reduces the consumption of energy, improves magnetic flux.
By above table as can be seen that comparative example 1 and comparative example 1, are made using Fe-based amorphous material
Inductance coil and existing inductance coil, in the case of frequency, voltage constant, inductance can reduce with the increase of electric current, and
Fe-based amorphous material is increased with the increase of electric current.Existing inductance coil inductance is smaller, with the increase of electric current, easily
There is the unstable phenomenon for passing through of electric current, spillage of material is very fast, so as to increased energy ezpenditure；And by the technical program heat at
The inductance coil that Fe-based amorphous material after reason is made, inductance is larger, the crystallinity increase after heat treatment so that Fe-based amorphous material
The internal quantity of electric charge that more in order, unit area the passes through increase of material, electric current increase, electric current passes through relatively more stable, spillage of material
Slowly, energy ezpenditure reduces.
By above table as can be seen that comparative example 1 and comparative example 2, nitrogen is relatively steady under normal temperature condition
It is fixed, but for nitrogen is with respect to argon gas under the high temperature conditions, relative to be not sufficiently stable, inductance can occur up and down with the change of electric current
The wild effect of floating, therefore, from the point of view of the security standpoint of heat treatment process, argon gas is safer.
Above-described is only embodiments of the invention, and the general knowledge such as known concrete structure and characteristic is not made herein in scheme
Excessive description.This application claims protection domain should be defined by the content of its claim, the specific embodiment party in specification
Formula etc. records the content that can be used for explaining claim.
