Magnetic materials are widely used in modern life and science and technology. The development of new magnetic materials and their application is an important aspect of modern high technology. New magnetic materials are constantly emerging. Next, I will introduce you to amorphous magnetic cores:
Characteristics and uses of amorphous magnetic material
The emergence and application of amorphous magnetic materials are mainly based on saving energy and improving the efficacy of equipment or components. Amorphous magnetic materials are mainly used in two aspects: one is for electronic components, and the other is It is a power supply device. People always hope that it has high efficiency and low loss when using instruments and equipment. In the current era of world energy crisis, it will be of great significance.
The structural characteristics of amorphous materials make amorphous materials have some excellent properties and uses:
(1) Since amorphous alloys do not have a crystalline structure, there are no grain boundaries, dislocations, interplane slips, grain defects and local heterogeneity of contractures. At the same time, due to the constituent atoms Random close packing and high coordination number, which must be high strength, hard hardness and good corrosion resistance in mechanical properties (because grain boundaries and chemical inhomogeneity are the main locations that are eroded first).u200bu200b
(2) Due to the irregular spatial arrangement of atoms, there is no inherent symmetry of the crystal system. Amorphous material
s are more uniform and tougher than crystalline materials, and are isotropic. The magnetic anisotropy constant K is small. Soft magnetic performance is good. Due to the high sensitivity of the anisotropic magnetic field, it can be used to form a high-sensitivity magnetic field meter or magnetic flux sensor. Stress magnetic effect type high-sensitivity stress sensors and magnetostrictive effect type mechanical sensors have been developed successively.u200bu200b
(3) Since the amorphous alloy is doped with glassy elements, the resistivity p is high, and the eddy current loss is low. Compared with the crystalline alloy, under the same conditions, the use frequency can be increased. Effective use of this It is possible to develop a fast-response sensor that is difficult to achieve with magnetic crystals.u200bu200b
(4) Curie temperature Tc (about 300-400℃) is higher than that of ferrite, but not comparable to metal materials. When the Curie temperature is reached, its composition can be arbitrarily determined. Therefore, it is expected to develop a fast response temperature sensor by utilizing the magnetic properties. In summary, the characteristics of amorphous alloy magnetic materials are: high strength, hard hardness, good ductility, high resistivity, low coercivity, high permeability, low loss, corrosion resistance, radiation resistance, etc. Advantages, especially amorphous alloys such as Fe80B20 and Fe5Co70Si15B10, they have the rare advantage that the mechanical properties are particularly hard and 'hardCompared with the excellent characteristics, it also has a wide range of applications in real life.
