High Temperature Hybrid Permanent Magnet |
| 摘要 |
In at least one embodiment, a hybrid permanent magnet is disclosed. The magnet may include a plurality of anisotropic regions of a Nd—Fe—B alloy and a plurality of anisotropic regions of a MnBi alloy. The regions of Nd—Fe—B alloy and MnBi alloy may be substantially homogeneously mixed within the hybrid magnet. The regions of Nd—Fe—B and MnBi may have the same or a similar size. The magnet may be formed by homogeneously mixing anisotropic powders of MnBi and Nd—Fe—B, aligning the powder mixture in a magnetic field, and consolidating the powder mixture to form an anisotropic hybrid magnet. The hybrid magnet may have improved coercivity at elevated temperatures, while still maintaining high magnetization. |
