METHOD FOR PRODUCING NANOCOMPOSITE MAGNET USING ATOMIZING METHOD |
摘要 |
Iron-based rare earth alloy nanocomposite magnetic powder is produced by an atomization method, and contains >=2 ferromagnetic crystal phases. The average size of the hard crystal phase is 10-200nm and the average size of the soft magnetic phase is 1-100nm. The powder has the composition (Fe 1-mT m) 100-x-y-z-nQ xR yTi zM n. T : Co and/or Ni; Q : B and/or C; R : rare earth metal and/or yttrium; M : Nb, Zr, Mo, Ta and/or Hf; x : 10-25 atom%; y : 6-10 atom%; z : 0.1-12 atom%; m : 0-0.5; n : 0-10 atom%. Independent claims are also included for (1) a bonded magnet containing the powder; (2) the manufacture of the powder; and (3) the manufacture of the bonded magnet. |
