Nanocrystalline core: amorphous strip 'secret'! What is a crystal strip? In daily life people touch information generally has two kinds: one kind is a crystalline material, another kind of amorphous materials. Crystalline materials, refers to the data inside the atom comply with the laws of must. Conversely, inside the atom is put in a random state, amorphous materials, metal, its internal atoms are put orderly, go to crystal materials. Scientists have discovered that the metal melting, internal atoms in the active state. Once the metal started to cool, atoms with temperature drop, but slowly according to the will of crystalline state laws in order to put together, constitute a crystal. If the fast cooling process, the atoms could rearrange was condensation, thus was born the amorphous alloy, the preparation of amorphous alloy is a kind of rapid condensation 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, amorphous strip. Primary characteristics of amorphous or crystalline 1, amorphous alloy crystal by ferromagnetic elements ( Fe、Ni、Co) And amorphous elements ( 如果,B, C) Combination; 2, amorphous or crystalline characteristics: low coercive force, high permeability, low loss, low saturated magnetic induction, high resistivity, high temperature stability, good frequency characteristic and the adjustable magnetic function; 3, after proper annealing, iron base the wafer ( Belt) Than the orientation of silicon steel sheet ( Belt) Show a lower than the total loss. The use of amorphous strip. Compared with amorphous alloy, amorphous alloy in terms of physical, chemical and mechanical functions change significantly. Mainly iron amorphous alloy as an example, it has the characteristic of high saturation magnetic induction intensity and low loss. Due to such features, the amorphous alloy materials in electronics, aerospace, aviation, machinery, microelectronics has wide use in many fields such as space. Used in the aerospace field, for example, can reduce power supply equipment and component, add payload. Used for civilian power, electronic equipment, can greatly reduce the power volume, advance efficiency and anti-interference ability. Tiny core can be used a lot in general affairs in the digital network ISDN transformer. Amorphous strips used to make the super market and sensor tag library security systems. Amorphous alloy magical effect, has the broad market prospect. At present, with electronic technology to develop in the direction of high frequency, miniaturization, amorphous superfine crystalline soft magnetic alloy material has been made into a variety of magnetic device to replace silicon steel, ferrite and permalloy used in electric power industry, electronic industry and power electronic technology, used for current transformer, high-power switching power supply, inverter power supply and SPC switching power transformer, reactor, filter, transformer, and sensor etc.
One increasingly popular managerial tactic to improve problem-solving performance of nanocrystalline cores is to increase the connectedness, or what academics call clustering, of the organization
