Hf—Co—B alloys as permanent magnet materials |
| 摘要 |
An alloy composition is composed essentially of Hf2-XZrXCo11BY, wherein 0<X<2 and 0<Y≦1.5. Moreover, an alloy composition is composed essentially of ferromagnetic Hf2-XZrXCo11BY, wherein 0≦X<2 and 0<Y≦1.5, and has a nanoscale crystalline structure comprising at least one non-equilibrium phase. The alloys can be melt-spun with in-situ and/or ex-situ annealing to produce the nanoscale crystalline structure. |
