Abstract
Sm2Fe17N3−δ is a promising permanent magnet material but disproportionation above 650 °C means that only low‐temperature processing can be considered. Sintering micron‐size Sm2Fe17N3−δ powder with the soft, low‐melting metals Zn, Bi, Sn, and Al has been investigated. Good results are obtained with zinc. A coercivity of 0.6 T and a maximum energy product of 84 kJ/m3 (10.5 MGOe) have been obtained. Zn7Fe3 is formed as a secondary phase.This publication has 9 references indexed in Scilit:
