Present work describes the magnetic properties of Nd-Fe-B melt-spun ribbons which have lower Nd content than the Nd<sub>2</sub>Fe<sub>14</sub>B compound. The studied alloys were (1) Nd<sub>x</sub>Fe<sub>94-x</sub>B<sub>6</sub>, (2) (Fe<sub>3</sub>B)<sub>1-x</sub>-(Nd<sub>2</sub>Fe<sub>14</sub>B)<sub>x</sub> and (3) Fe<sub>1-x</sub>-(Nd<sub>2</sub>Fe<sub>14</sub>B)<sub>x</sub>. The grain refinement were underwent by studying the conditions of annealing for crystallization. It results in disappearing noticeable knicks in the demagnetization curves, which is attributed to precipitations of α-Fe and Fe<sub>3</sub>B phases. The Nd<sub>8</sub>Fe<sub>86</sub>B<sub>6</sub> melt-spun ribbon annealed at 650°C for 30 min exhibits the highest (<i>BH</i>)<sub>max</sub> of 126kJm<sup>-3</sup>(15.8MGOe). The V addition is effective for improving the coercivity.
