Conclusions

  1. 1.

    A study was made of a simplified method of manufacture of sintered samarium-cobalt permanent magnets based on the use of “overmilled” starting SmCo5 powders.

  2. 2.

    It is shown that the key critical parameter in the simplified process is the total amount of the rare-earth component in the starting charge.

  3. 3.

    The process investigated ensures a reliable reproduction of magnetic characteristics of sintered SmCo5 permanent magnets within the following ranges: Br=8400±250 G,BHc=6650±384 Oe, and (BH)max=15.2±0.93 MG-Oe. The maximum level of magnetic energy attains 23 MG-Oe.
