| 简介 |
Disclosed is a process for producing an R-T-B-type [wherein R represents at least one metal selected from Nd, Pr, Dy and Tb and essentially contains 4 to 10% by mass of Dy or Tb, T represents a metal essentially composed of Fe and B represents a boron atom] rare-earth permanent magnet, which utilizes, as a raw material, an alloy material for an R-T-B-type rare-earth magnet, wherein the alloy material comprises an R-T-B alloy and a metal powder. The process enables the production of an excellent R-T-B-type rare-earth permanent magnet that has high coercivity (Hcj) and is less likely to undergo the reduction in magnetization (Br). |
