Microstructure and Magnetic Properties of Pr₂(FeCo)₁₄B/α-(FeCo) Nanaocomposite Permanent Alloys

State Key Laboratory for Advanced Metals and Materials, UST Beijing, Beijing 100083

摘要: 利用單輥快淬法制備了由硬磁相Pr₂(Fe,Co)₁₄B和軟磁相α(Fe,CO),Pr₂(Fe,Co)₁₇組成的納米晶復合永磁材料.用X射線衍射、室溫磁性能測量和熱磁分析等,研究了Pr_7.5Dy₁Fe_80-xCo_x Nb₁B_4.5(x=10,15)合金快淬帶在不同溫度下不同時間退火后的組織和磁性能變化規律.結果表明,快淬帶在700℃退火6h后,永磁性能仍保持較高的水平,說明同時添加Co和Nb,有可能提高納米晶復合永磁合金的熱穩定性.

Abstract: The nanocomposite permanent alloys which is composed of Pr₂(Fe,Co)₁₄B and α-(Fe,Co) and Pr₂(Fe,Co)₁₇ were made by single-roller rapid quenching. The X-ray diffraction method, room-temperature magnetic measurement and thermal magnetic analysis were used to analyze the microstructure and magnetic properties of Pr_7.5Dy₁Fe_86-xCo_xNb₁B_4.5(x=10,15) alloys. Magnetic properties of the ribbons annealing at different temperature and for various time were extensively studied. Permanent magnetic properties still keep a high level in the ribbons that were annealed at 700℃ for six hours. This result implies that thermal stability of the alloys may be enhanced by adding Co and Nb at the same time.
