Abstract
Neutron diffraction has been used to determine the location and concen tration of C in Nd2Fe17 and in a Si substituted alloy. The results ind icate that two carbide phases exist. One contains nearly three C atoms per formula unit, while the other has a much lower concentration. The high C phase contains C only on the 9 e sites, but the low C phase ap pears to contain C on the tetrahedral 18 g site. The changes in intera tomic distances and cell volume are associated with the different site occupancies. (C) 1995 American Institute of Physics.
