Compaction of nano-structured SmCo/Fe magnets

Nanostructured SmCo/Fe magnets are prepared by cold isostatic pressing method at 35 MPa followed by combustion driven compaction at 2 GPa at room temperature. The direction of compaction parallel and perpendicular to c-axis alignment of the green compact is investigated using X-ray pole figures. For the sample compacted perpendicular to the c-axis, an elongation of the intensity pattern is observed for the [002] pole indicating a partial orientation in that direction. On the other hand, no preferential orientation is observed for the sample compacted parallel to the alignment axis. Texture analysis is then used to quantify the degree of alignment.
