Effects of Co, Mo, and Ni on magnetic properties in 3Si–0.1Sn–0.08Sb alloyed non-oriented electrical steels

With the addition of Co, Mo and Ni to highalloyed non-oriented electrical steels with 3Si–0.1Sn– 0.08Sb, Ni increased grain size more than Co and Mo. A very low level of core loss (W15/50 = 2.2 W/kg) and high magnetic induction (B50 = 1.7 T) were obtained in the Ni added steel. However, Co and Mo deteriorated the magnetic properties substantially. With respect to the texture effect on magnetic properties, core loss decreased and magnetic induction increased proportionally to texture factor (ratio of the sum of cube and Goss texture to c fiber), while correlations of anisotropies of core loss and magnetic induction to the texture factor appeared parabolic
