Abstract
Nd-Fe-B magnets are used in wide range of industrial applications. In this research we studied the possibility of producing bulk Nd-Fe-B magnetic compact by using the direct cylinder explosive compaction. After compaction the density of compact was measured by the Archimedes method. Highly dense compact (> 98% relative density) without cracks was obtained by this technique. A concentric hole was observed at center of some compacts. The magnetic properties of the compact are Br=7.95KG, iHc=10.5kOe, (BH)max= 14MOe, and these values are same as those before explosive compaction.
