What is an amorphous alloy transformer

2019-04-02 09:09:56

We start with amorphous materials. There are two kinds of materials that people come into contact with in daily life: one is crystalline and the other is amorphous. The so-called crystalline material means that the atomic arrangement inside the material follows a certain law. On the other hand, if the internal atom arrangement is in an irregular state, it is an amorphous material, and the general metal, whose internal atoms are arranged in order, belongs to a crystalline material. Scientists have discovered that after the metal is melted, the internal atoms are active. Once the metal begins to cool, the atoms will slowly and orderly follow a certain crystal state to form crystals as the temperature drops. If the cooling process is fast, the atoms are not ready to be re-arranged and solidified, thereby producing an amorphous alloy. The preparation of the amorphous alloy is a rapid solidification process. The high temperature liquid in a molten state is sprayed onto a high speed rotating cooling roll. The alloy liquid is rapidly cooled at a rate of one millionth of a second, and the alloy liquid of 1300 ° C is lowered to room temperature in only one thousandth of a second to form an amorphous ribbon.

Amorphous alloys have undergone significant changes in physical, chemical and mechanical properties compared to crystalline alloys. Taking an iron-based amorphous alloy as an example, it has the characteristics of high saturation magnetic induction and low loss. Due to such characteristics, amorphous alloy materials have a wide application space in many fields such as electronics, aerospace, aerospace, machinery, and microelectronics. For example, in the aerospace industry, it can reduce the power supply, equipment weight and increase the payload. It can be used for civil power and electronic equipment, which can greatly reduce the power supply volume, improve efficiency and enhance anti-interference ability. Miniature iron cores can be used in a large number of transformers in ISDN. Amorphous strips are used to make sensor tags for supermarkets and library anti-theft systems. The magical effect of amorphous alloy has broad market prospects.
