Amorphization of Co-Nb Magnetic Alloys by Mechanical Alloying
-
Abstract
Formation of amorphous Co-Nb system by mechanical alloying (MA) in the composition range of Co25Nb75-Co70Nb30 was studied by X-ray diffraction. Magnetic properties of the mechanically alloyed Co70Nb30 powder were measured. The variation in Hc curve with milling time can be explained by two-stage mechanism involved in the milling process. The results show that the amorphous powder prepared by MA is of good soft magnetic properties.
