Phase formation and crystallographic investigations of the Dy-Fe-(B, N) system

The effect of nitrogen on the stability of rare earth:iron 2:17 and rare earth:iron:metalloid 2:14:1 phases has been examined. X ray diffraction and Mössbauer spectroscopy suggest that a 2:14:1 type phase is unlikely to form with nitrogen even in the presence of boron. Thermal analysis found that boron increases the nitrogen absorption significantly.
