Abstract: Fe-based amorphous alloy materials are the most widely used systems in amorphous alloys as magnetic functional materials with excellent performance. Elimination of internal stress through annealing treatment is a key process to improve soft magnetic properties. In this work, the soft magnetic properties of the Fe80Si9B11 amorphous ring cores wrapped with copper strips were investigated by a rapid annealing manner. The experimental results indicate that a reasonable amorphous/copper thickness ratio, annealing temperature and time can make the temperature field more uniform due to the good thermal conductivity of copper can enhance heat transfer, which reduces the coercivity difference at different positions of amorphous iron core, improves the initial permeability of amorphous iron core, and then improves the heat treatment efficiency and soft magnetic properties.
