Abstract

The structure and magnetic properties of SmyFe(100-1.5)yC(0.5y)(y=8 similar to 20) alloys prepared by mechanical alloying (MA) from Sm, Fe and graphite have been investigated systematically. In order to improve hard magneticproperties of the alloys prepared by mechanical alloying, a new method consisting of re-milling and re-annealing was developed. After being re-milledand re-annealed, the Curie temperature T-C of the Sm-Fe-C alloys changes. The T-C of 2:17 phase increases, whereas the T-C of 2:14:1 phase decreases. After being re-annealed at low temperatures, the grain sizes of hard phases are smaller than those in the alloys annealed at high temperatures. The effects of Co or Ti substitution for Fe are studied.
