We start with amorphous materials, in daily life, people contact materials generally have two kinds: one is crystalline material, and the other is amorphous material. The so-called crystalline material, refers to the internal atomic arrangement of materials follow certain rules. On the contrary, the internal atomic arrangement is in an irregular state, and then the amorphous material. The general metal, whose internal atoms are arranged orderly, belong to crystalline material. Scientists have discovered that the metal atoms are active after melting. As soon as the metal begins to cool, the atoms are arranged in an orderly fashion according to certain crystalline states as the temperature drops, forming crystals. If the cooling process is very fast and the atoms are not rearranged, they are solidified, thus producing amorphous alloys, and the preparation of amorphous alloys is a rapid solidification process. The molten molten steel in molten state is sprayed onto the high speed rotating cooling roll. The molten steel is cooled rapidly at a rate of one million per second, and the molten steel at 1300 degrees is reduced to below 200 degrees in only 1/1000 seconds to form amorphous ribbons.

Compared with crystalline alloys, amorphous alloys show remarkable changes in physical properties, chemical properties and mechanical properties. As an example, amorphous alloy with Fe element is characterized by high saturation magnetic induction and low loss. Because of this characteristic, amorphous alloy materials have wide application space in many fields, such as electronics, aviation, aerospace, mechanical, microelectronics and so on. For example, for aerospace, it can reduce power, equipment weight, and increase payload. For civil power and electronic equipment, it can greatly reduce the volume of power supply, improve efficiency, and enhance anti-interference ability. Micro core can be widely used in integrated services digital network ISDN transformer. Amorphous ribbons are used to make sensor labels for supermarket and library anti-theft systems. Amorphous alloy magic effect, has broad market prospects.
