摘要：

Efect of ball scribing on relative permeability of conventional grain-oriented(CGO)and high permeability grain-oriented(HGO)electrical steel was investigated.The samples were scribed with spacing of 2 mm,4 mm,8 mm and 16 mm.The results show that after ball scribing with 16 mm width at 1.0 T,relative permeability of both℃GO and HGO steels was increased by 109%and 80%,respectively.Relative permeability rises as the scribing space increases,with the movement of the peak value of relative permeability to a higher flux density.Relational models describing relative permeability and flux density were constructed with high accuracy based on experimental data.The experimental data curves were analyzed during the magnetizing process.
