ball milling magnetic

In this study, we demonstrate the synthesis of an Fe78Si9B10P3 amorphous alloy by three pathways: mechanical alloying, melt-spinning and a combination of melt-spinning and ball milling. Microstructure, thermal stability and soft magnetic properties of the melt-spun and mechanically alloyed powders are comparatively studied. Ball milling of previously melt-spun samples led to an amorphous ...

The Effect of Ball Milling on Magnetic Properties of Iron

The Effect of Ball Milling on Magnetic Properties of Iron

The effect of ball milling on magnetic properties of it was researched. Such results were concluded from experiments. With increasing the milling time, the powder size decreased and core loss increased. The effect of milling to permeability was not obvious. With milling 2 hours magnetic properties of powder core were best enhanced.
