Disordered arrangement of atoms in three-dimensional space is topology, there is no long-range periodic, but in a few atomic spacing range, the arrangement of atoms still has certain regularity, so you can think of amorphous alloy atomic structure for "long-range disorder, short-range order". Usually define amorphous alloy short-range ordered area is less than 1.5 nm, which no more than 4-5 atomic spacing, which differs from nanocrystalline or microcrystalline = short-range ordered topological short range can be divided into chemical short range order and orderly. Crystal is a typical ordered structures, the gas, liquid and amorphous solids are disordered structure. Amorphous solid materials, including amorphous inorganic materials such as glass, amorphous polymers and amorphous alloys (metallic glass) and other types.

Can produce amorphous metal, it has been a modern scientists decipher a difficult problem. Scientists have discovered that the metal melting, internal atoms in the active state. A metal begins to cool down, but the atoms as the temperature drop, but slowly is arranged according to certain crystalline state regulation, the formation of crystal. If the fast cooling process, the atoms could rearrange is solidified, thus was born the amorphous alloy. Visible, one of the key technology of amorphous alloy, is the problem of how to rapid cooling. The preparation of amorphous alloy is a kind of rapid solidification process. Would be in a molten state of high temperature molten steel into the high-speed rotating on the cooling of the roller. Molten steel at millions of degrees per second cooling rapidly, with only one over one thousand of a second time will fall below 200 ℃ 1300 ℃ of molten steel, forming of amorphous strip.

Developed countries technology of amorphous alloy manufacturing technology have been strictly enforced blockade. Scientists in China after nearly 20 years of unremitting efforts, finally in the period of the ninth five-year plan, implement the technological leapfrogging in the field of preparation of amorphous alloy, mastered the core technology with independent intellectual property rights. And made a breakthrough in amorphous alloy industrialization progress, formed the annual output of 4000 tons of industrial scale. Fill in the metallurgical industry in our country in a technology gap. Amorphous alloy compared with amorphous alloy, in terms of physical properties, chemical properties and mechanical properties are changed markedly. Mainly iron amorphous alloy as an example, it has the characteristics of high saturation magnetic induction intensity and low loss. Modern industrial multi-purpose it manufacturing distribution transformer iron core. At present our country has been able to according to the market need, production of various specifications of amorphous strip, brightness of up to 220 mm. This kind of amorphous alloy transformer, compared with the traditional silicon steel core transformer no-load loss to reduce 60% ~ 80%, has obvious energy saving effect. If all the existing distribution transformer in China for amorphous alloy transformer, so can save the national electricity 9 billion kilowatt hours a year, this means that each year can build a 1 million mw thermal power plant, less to reduce 3.64 million tons of coal, to reduce carbon emissions, such as more than 900 cubic meters. In this sense, the amorphous alloy was praised as "green material".

Amorphous alloy material, also be widely used in electronics, aerospace, aviation, machinery, micro-electronics, etc in many fields, for example, used in the aerospace field, can reduce power supply, equipment weight, increase the payload. Used for civilian power, electronic equipment, can greatly reduce the power volume, improve efficiency, enhance anti-jamming capability. Tiny core can be used in the integrated services digital network ISDN transformer. Amorphous strips used to produce super market and sensor tag library security systems. Amorphous alloy magical effect, has broad market prospects. During the tenth five-year plan, China's science and technology workers will be in the field of amorphous alloy technology to make more contributions that have astonished the world.
