The grain sizes of these mechanical alloyed powders were about 10-15 nm. Density of the specimen sintered at 900degreesC was about 98%, and grain size of the specimens ranged from 80 to 200 nm. The spontaneous magnetization for the alloy powders and all sintered parts areal most the same at about 214 emu/g. The nanostructured Fe-Co part consolidated at 700degreesC for 5 min has a lowest coercivity (19 Oe), comparing with the parts consolidated at higher temperatures. (C) 2004 Elsevier B.V.
