Abstract
Disclosed is a method of manufacturing Fe-based soft magnetic powder for a high-frequency application. The method includes the steps of manufacturing Fe-9Al-6Si alloy powder; deforming the Fe-9Al-6Si alloy powder into a flake-like form using a high energy ball mill, and heat-treating the flake-like Fe-9Al-6Si alloy powder to relieve stress and be re-crystallized to have a super fine grain size. 0.1.about.5 weight percent of lubricant with respect to the alloy powder and balls of the high energy ball mill is added during the ball mill processing. A soft magnetic core made of the Fe-based powder is also disclosed.
