Abstract
The coercivity of the melt-spun pseudobinary (NdFe10Cr 2)1-x (Nd2B)x alloys, in which Nd2B represents a composition of Nd0.67B0.33, was systematically studied. It was found that significant coercivities are possible with optimal additions of the Nd-B composition at x =0.5-0.7. The as-spun (substrate velocity=10 m/s) coercivity increased from 0.1 kOe at x =0.0 to maxima of 7.0 and 7.5 kOe at x =0.5 and 0.7, due to the Nd2 Fe14B and a new Fe-Nd phase, respectively, as evidenced from thermomagnetic analysis and X-ray diffraction. Annealing the overquenched amorphous x =0.7 alloy led to the crystallization of the Nd2Fe14B phase, and a coercivity of 8.5 kOe was obtained
