This paper reports on RFe[sub 11[minus]x]Co[sub x]TiN[sub y] (R:Nd, Pr) compounds with ThMn[sub 12] type structure were synthesized through metallurgical processes such as melting, casting, pulverizing, and gas nitrogenation. Those compounds showed increases in magnetic induction (4[pi]lm), anisotropic field (Ha), and Curie temperature (Tc) by a nitrogenation as in the case of Sm[sub 2]Fe[sub 17]N[sub x] compound. The large values of 4P[pi]lm and Ha were observed in the range of nitrogen contents: 1 [lt] y [lt] 1.5. Cobalt substitution for iron also led to an increase in 4[pi]lm and Tc. The magnetic properties of magnetically aligned NdFe[sub 8]Co[sub 3]TiN[sub 1.3] powder were: 4[pi]lm = 15.0 kG, Ha - 75 kOe, Tc [gt] 600[degrees]C. The value of H[sub ci] was 5.9 kOe in the case of zinc bonded magnet prepared by the NdFe[sub 7.5]Co[sub 3.5]TiN[sub 1.4] powder. it is expected that the RFe[sub 11[minus]x]Co[sub x]TiN[sub y](R:Nd, Pr) compounds have potential applications for bonded magnets with high performance.
