摘要

The Fe-rich Fe-B-Cu system alloys are hopeful for the apply as a new type soft magnetic material in both electron and information fields because of its high permeability (mu(e)), low coercivity (H-c), high saturation magnetization (M-s) and low loss cost (W). However, the poor glass forming ability (GFA) and difficult structure-controlled which hinder the progress of industrializations and applications. Therefore, the transition group and big atom size element Hf is introduced into Fe86B13Cu1-xHfx alloys for partially replacing of the seeds and clusters element Cu, the result proves that Hf plays a positive role in perfecting GFA, enhancing thermal stability, improving structure-controlled, and impeding intermediate compounds. Both Fe86B13Cu0.5Hf0.5 and Fe86B13Cu0.4Hf0.6 asquenched ribbons exhibit an entire amorphous structure and have the low M s values, after annealing by 723 K x 10 min, the latter alloy shows a better structure-controlled on adjusting the uniform alpha-Fe/amorphous complex phase structure. In addition, the crystalized M-s value can be enhanced to the maximum of approximately 208 emu/g and the H-c value is effectively decreased from 9.3 to 2.3 A/m by an auxiliary annealing process of 673 K x 60 min applied the 1000 Gs magnetic field. The new developed Fe-B-Cu-Hf system alloys with good soft magnetic properties exhibit an acceleration applying progress in the Fe-rich alloys field.
