Grain Size Distribution on Annealed Silicon Steel

Article Preview

Abstract:

Silicon steel is a soft magnetic material very important to the highly industrialized society we live today. Application of magnetic field during annealing treatment has shown to affect positively the microstructure evolution of ferrous alloys leading to a more cost-effective final product. In order to evaluate the effect of magnetic field on the microstructure of GNO silicon steel, cold rolled samples were annealed at 800°C for 3, 15 and 30 minutes inside a 17 T magnetic field. According to the ESEM/EBSD results, the grains seemed to be the most influenced by magnetic field. Magnetic field seems not to affect nucleation of Goss grains but instead it seems to affect its boundary mobility.
