Earlier in this transformer cores requires soft magnetic materials is magnetized and demagnetized easily. (It also has a relatively high electrical resistance).Thus, the power loss of the transformer could be reduced if their core is fabricated from a single crystal. Thus the power loss of the transformer could be reduced if their core is fabricated from a single crystal. Unfornutaly the single crystal is expensive. Fabricated from sheets of polycrystalline alloy containing. anisotropic materials typically in cereals polycrystalline Sampling will focus on the results that their properties are isotropic, however, the development of metal anisotropy in polycrystalline. Through plastic deformation, for example by rolling. so,The body was identified by a combination of rolling plane for the body-centered cubic mixed. (Includes silicon-alloy steel mentioned earlier).The alloy transformer core silicon steel is being fabricated to extend direction. Aliged parallel to the direction of the applied magnetic field, the magnetic characteristics of the alloy can be further improved through a series of deformation and how to treat heat produced.
