摘要：

The permanent magnet alloy SmCo5 was synthesized by mechanical alloying directly from a SmF3 precursor. X-ray diffraction and electron microscopy showed that the mechanical alloying of SmF3 with Co and Ca resulted in the formation of nanocrystalline CaF2 and SmCo5 phases. Magnetic measurements of optimally heat treated powders showed a coercive force greater than 65 kOe. The high coercivity values appear to be a consequence of the nanoscale structure produced by mechanical alloying and heat treatment.
