| abstract | The present invention provides a kind of inexpensive without rare earth nano composite permanent-magnetic material and preparation method thereof.Chemical molecular formula of the low cost without rare earth nano composite permanent-magnetic material is Mn 53‑x Al 45 C 2 W x /(Fe 1‑ y Co y ) 2 B.Preparation method is: by pure metal raw material by Mn 53‑ x Al 45 C 2 W x Alloy name ingredient obtains master alloy spindle, and strip is made；Rapid tempering belt is subjected to vacuum heat treatment, obtains τ phase Mn 53‑x Al 45 C 2 W x Alloy；According to (Fe 1‑y Co y ) 2 B alloying component ingredient obtains master alloy spindle, and strip is made；By the Mn after heat treatment 53‑x Al 45 C 2 W x Melt spun ribbons and (Fe 1‑y Co y ) 2 B melt spun ribbons carry out high-energy ball milling, and nanometer crystal alloy powder is made；Fully dense nano composite permanent magnetic material is made in the nano composite powder discharge plasma sintering of acquisition；Nano composite permanent magnetic material through being sintered is subjected to thermal deformation, improves the degree of orientation, obtains low cost without rare earth aeolotropic without rare earth nano composite permanent-magnetic material.Permanent-magnet material prepared by the present invention is free of rare earth element, and cost of material, while simple process is effectively reduced, easily operated, is suitable for large-scale batch production. |
