Aa. Lukin, EFFECTS OF CHEMICAL INHOMOGENEITY AND TEXTURE ON MAGNETIC-PROPERTIES OF SINTERED (ND,DY,TB)-(FE,TI)-B SPECIMENS, Russian metallurgy. Metally, (2), 1996, pp. 94-99
The conditions of increased coercive force of the magnets based on the
(Nd. Dy. Tb)(15.7)Fe75.5Ti1.3B7.5 alloy are the maximum contents of D
y or Tb in the matrix hard-magnetic phase and increased concentration
of these elements near grain boundaries, especially, in the areas adja
cent to nonmagnetic phase constituents.
