Abstract
The magnetic and structural properties of FINEMET [Fe73.5Si13.5B9Nb3Cu1 wt%] amorphous powder were investigated after nitrification and mechanical milling. Fe-based amorphous powder were nitrified and crystallized simultaneously at 550 °C using by ammonia (NH3) gas. Nitrified powder exhibited iron nitride phase such as γ′-Fe4N, Fe3N, and α″-Fe16N2. Nitrified particles were more brittle than raw particles. As a result, nanometer-sized nitride powder was fabricated by high-energy ball milling method. The saturation magnetization (Ms) and coercivity (Hc) of nitrified powder were increased due to nitride phase.
