Abstract

The effects of Cu and P in the Fe_84-xSi₄B _12-yP_yCu_x (x = 0-0.9, y = 0-4) soft magnetic alloys on crystallization processes and magnetic properties were investigated. The apparent activation energy of Fe₈₄Si₄B ₈P₄ and Fe_83.3Cu_0.7Si ₄B₈P₄ amorphous alloys are also calculated. The results show that Cu and P additions favor the first crystallization reaction and inhibit the second one of Fe₈₄ Si₄ B₁₂ effectively. The saturation magnetic flux density B_s increases and the coercivity H_c decreases with increasing Cu content in the range of 0-0.9%. The simultaneous additions of Cu and P result in a good combination of high saturation magnetic flux density and low coercivity.
