Cellular microstructure development in Sm(Co, Fe, Cu, Zr) 8. 35 alloys

OSTI ID:6705889
TEM studies of Zr-containing 2:17-type permanent magnet alloys show that the cellular microstructure develops from a high-temperature 2:17R phase, first by the precipitation of Sm-depleted, Zr-rich 2:17H platelet phase, then by the precipitation of Cu-rich, Fe- and Zr-depleted 1:15 boundary phase. These results are supportive of, but also suggest refinements to, a model proposed earlier for the metallurgical behavior of these alloys.
