Commercially available Nd-Fe-B melt-spun ribbons (MQ powders) were consolidated at temperatures ranging from room temperature to 573 K in ambient atmosphere by the compression shearing method. The resultant bulk materials consisted of the Nd{sub 2}Fe{sub 14}B phase together with a small amount of the soft magnetic {alpha}-iron phase. The bulk material consolidated at room temperature was magnetically isotropic as was the case for the MQ powders. On the other hand, the bulk material consolidated at 573 K was found to be magnetically anisotropic and showed a remanence of 9.2 kG, higher than that of the MQ powders.
