Abstract

Abstract: In order to prepare cobalt-based amorphous alloys with low permeability and high rectangular ratio and low coercivity, Fe_3.85Co_66.18Si_14.5Ni_0.97B_14.5 amorphous alloy strips were subjected to different heat treatments and then their microstructure and properties were tested and analyzed. The results show that the relaxation enthalpy of the cores decreases after stepwise longitudinal magnetic heat treatment, while the densities and orderliness increase, and the alloys annealed below the crystallization temperature remain amorphous. The stepwise longitudinal magnetic heat treatment significantly improves the magnetic properties of the cores, and the best properties are achieved when the traditional heat treatment temperature is 480 ℃, with a coercivity of 0.17 A/m, a rectangular ratio of 96.81%, and an effective magnetic permeability of 5675.05 at 1 kHz. At this time the magnetic domains are in the form of regular slats and oriented at an angle of 12.8° to the external magnetic field. Based on Bertitto model, the loss separation is found to satisfy the equation:P_v=11.05×f×B^0.9814_m+0.7495×f²×B²_m.

Key words: stepwise longitudinal magnetic heat treatment, cobalt-based amorphous alloy, magnetic domains, magnetic properties, loss separation
