摘要：
A permanent magnet alloy contains 10-40 wt.% R, where R is at least one component selected from Y and rare earth elements, 0.1-8 wt.% B, 50-300 ppm O, and balance Fe. It is manufactured by melting a raw material within these composition ranges, casting it to a block, which is pulverised to an average particle size of 2-10 mm, compressing the powder while applying a magnetic field, and sintering the compact at 1000-1200 deg.C for 0.5-5 hours. The raw material can also include not more than 20 wt.% at least one component selected from Co, Cr, Al, Ti, Zr, Hf, Nb, Ta, V, Mn, Mo and W.
摘要（中）：
永磁合金含有10-40重量％的R，其中R是选自Y和稀土元素中的至少一种成分，0.1-8重量％B，50-300ppm O，余量为Fe。 通过在这些组成范围内熔化原料制成，将其铸造成块，将其粉碎至平均粒径为2-10mm，在施加磁场的同时压制粉末，并将成形体烧结成1000-1200 摄氏0.5-5小时。 原料还可以包含不超过20重量％的选自Co，Cr，Al，Ti，Zr，Hf，Nb，Ta，V，Mn，Mo和W中的至少一种。
