Consolidation of Nd–Fe–B melt-spun ribbon by compression shearing method

Consolidation of Nd–Fe–B melt-spun ribbon by compression shearing method

Commercially available Nd–Fe–B melt-spun ribbons (MQ powders) were consolidated at temperatures ranging from room temperature to 573K in ambient atmosphere by the compression shearing method. The resultant bulk materials consisted of the Nd2Fe14B phase together with a small amount of the soft magnet...

Zusammenfassung:Commercially available Nd–Fe–B melt-spun ribbons (MQ powders) were consolidated at temperatures ranging from room temperature to 573K in ambient atmosphere by the compression shearing method. The resultant bulk materials consisted of the Nd2Fe14B phase together with a small amount of the soft magnetic α-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 573K was found to be magnetically anisotropic and showed a remanence of 9.2kG, higher than that of the MQ powders.
