Conclusions In alloys of the Fe−Nd system obtained by quenching from the liquid state, we observe the following phases: for (28–58)% Fe−P1 (TC≅240°C); for 〈28% Fe−P2 [TC=(220±5)°C]. In the alloy based on Nd containing ∼5% Co and 23% Fe, we observe the P3 phase with TC=160°C (tentatively amorphous). The presence of the P1 phase in Nd-(37–58)% Fe alloys is responsible for the increase in the coercive forceIHC up to 0.4 MA/m. During annealing, the amount of P1 phase is reduced, a stable Nd2Fe17 phase appears, which is accompanied by a sharp decrease in the coercive force. In the alloy based on Nd containing 5% Co and 23% Fe, after annealing the P4 phase is formed (TC=340°C, Ha≥4.8 MA/m), which causes the appearance of the coercive forceIHC=1.52 MA/m.
