Abstract:

The glass forming ability and magnetic properties were investigated for adding neodymium to the Fe_71-xNb₄B₂₅Nd_x (x=0, 3, 5, 7,10) alloys prepared by copper suction casting. It was found that proper neodymium (x=5~10 at.%) could improve glass forming ability of Fe-Nb-B alloys effectively. Bulk amorphous Fe₆₆Nd₅B₂₅Nb₄ and Fe₆₄Nd₇B₂₅Nb₄ samples were obtained and presented high thermal stability and good soft magnetic properties. The value of activation energy of the first crystallization peak for the bulk amorphous alloy Fe₆₄Nd₇B₂₅Nb₄ is 683 kJ/mol.
