What is amorphous alloy

Speaking of amorphous materials, we first come in contact with people in everyday life, there are generally two kinds of materials: one is a crystalline material, the other is amorphous material. The so-called crystalline material, refers to the material within the atomic arrangement to follow certain rules. On the contrary, the internal atomic arrangement in a random state, the amorphous material, the general metal, the internal atoms arranged in order, all belong to the crystalline material. Scientists found that after the metal is melted, the internal atoms are active. Once the metal begins to cool down, the atoms will gradually decrease in temperature, and slowly and orderly arranged according to certain crystalline regularities to form crystals. If the cooling process is very fast, the atoms are not too late to rearrange and are solidified, resulting in amorphous alloys. The amorphous alloy used is a rapid solidification process. High-temperature molten steel in the molten state is sprayed onto the high-speed rotating cooling roll. Rapid cooling of molten steel at a rate of one million degrees per second, only the time of one thousandth of a second will be 1300 ℃ molten steel below 200 ℃, the formation of amorphous strip.

Compared with crystalline alloys, amorphous alloys have significant changes in physical properties, chemical properties and mechanical properties. Take the 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 range of applications in many fields such as electronics, aviation, aerospace, machinery, microelectronics and the like. For example, for the aerospace field, you can reduce the power, equipment weight, increase the payload. For civil power, electronic equipment, can greatly reduce the size of the power supply, improve efficiency and enhance anti-interference ability. Micro-core can be widely used in Integrated Services Digital Network ISDN transformers. Amorphous strips are used to make sensor tags for supermarkets and library security systems. Amorphous alloy magic effect, with broad market prospects.
