Abstract

Nanocrystallization effect of primary Fe₂₃M₆-type phase (M: C or B) on magnetic properties of Fe-based bulk metallic glass (BMG) has been investigated. Under controlled microstructural modification with Fe₂₃M₆-type phase, the soft magnetic properties of Fe _76.5C₆Si_3.3B_5.5P_8.7 (at.%) BMG were significantly improved: saturation magnetization (M_s) and initial permeability (μ_i) of the alloy were dramatically enhanced from 1.35 T and 3500 to 1.57 T and 9890, respectively. The present study about introducing medium range atomic orderings and nanocrystallization of Fe₂₃M₆-type structure in amorphous matrix suggests a strategy to enhance the soft magnetic properties of ferromagnetic BMGs having the primary crystallized phase Fe₂₃M₆. This result provides useful insight to develop soft magnetic nanocrystalline materials, stating from BMG precursor with large glass forming ability.
