Phase analysis of liquid-phase sintered Co 5 Sm magnet compacts

The purpose of this work is to determine the phases present in liquid-phase sintered Co 5 Sm magnets. Specimens sintered at 1100°C and given subsequent thermal treatments were examined by optical metallography, electron microprobe, and X-ray diffraction techniques. The results of this work suggest that these materials do not exhibit an equilibrium configuration of phases.
