摘要：

Effects of V or Mo addition on microstructure and magnetic properties or Nd-Dy-Fe-Co-B sintered magnets have been studied. It is shown that these additives increase the intrinsic coercivity of cobalt-containing NdFeB-type sintered magnets, serving to reduce the amount of Dy required for thermal stability. Corrosion resistance in a humid atmosphere is also improved by these elements. © 1990 IEEE
