Rare earth, iron carbon permanent magnet alloys and method for producing the same
A permanent magnet alloy having at least one light rare earth element, iron and carbon. The alloy has a cellular microstructure of at least two solid phases with a Fe14R2C1 magnetically hard, tetragonal major phase surrounded by at least one minor phase. The light rare earth element may be Pr or Nd....

| description | A permanent magnet alloy having at least one light rare earth element, iron and carbon. The alloy has a cellular microstructure of at least two solid phases with a Fe14R2C1 magnetically hard, tetragonal major phase surrounded by at least one minor phase. The light rare earth element may be Pr or Nd. At least one heavy rare earth element, such as Dy, may be used. Boron may be included in the alloy. The alloy is produced by casting and heating to form the Fe14R2 (C,B)1 magnetically hard, tetragonal major phase. |
