These cobalt-containing phases remain after the alloy processing to produce the sintered magnet and reduce the intrinsic coercivity. These phases have also been previously identified [ 16].
This phase has also been previously identified [17]. Although the Curie temperature is enhanced, the intrinsic coercivity of the cobalt-containing magnets is reduced due to Pr3 FeCo and Pr FeCo 2 phases. The addition of 0. In general, the addition of cobalt and niobium improves the resistance to corrosion of the praseodymium-based HD permanent magnets.
