Effect of annealing parameter on microstructure and magnetic properties of cold rolled non-oriented electrical steel

摘要：

The microstructure and magnetic properties of cold rolled non-oriented electrical steel,annealed at 200.1 000 ℃ for 0.240 min with different heating rates,were investigated by optical microscopy,scanning electron microscopy,Epstein frame,and transmission electron microscopy.The results show that the magnetic properties of cold rolled non-oriented electrical steel can be improved by controlling the annealing process to obtain uniform coarse grains with critical sizes after the recovery,recrystallization and growth of grains.Additionally,the annealing temperature influences the magnetic properties more significantly than annealing time,and with the increase of heating-up rate during the annealing process,the magnetic properties of the cold rolled non-oriented electrical steel increase.
